I just completed my multiwii quadcoptor and nrf24lo1 transmitter , works great , appreciate your contributions, it would be great if you can kick Start new project with kk2.1.5 (Arduino based ) with LCD , I not familiar with Arduino programming, however I'll provide my full support and share over internet ......
Very useful video.. can I ask that which program is used for 3d animation??
Electronoobs /Thanks...

I know it has been said before but thank you for everything you do for the IGBT community!
On that note what is an IGBT's Q?
#Resist ...err, I mean resistance
@@InsideOfMyOwnMind quad, I'm guessing. There's one component called an H-bridge, which uses 4 control inputs with a total of 4 functions. Quad means 4. The 4 functions are forward, reverse, brake, and no current.

Haha i laughed so hard on that
Wow your graph really helps to memorize the rest of the video, great work
Great review for people already family, too.
And as always, very good and informative graphics.
I found electronoobs channel more useful as it explain electronics deep down. Thank you for the effort. God bless you.
Thank you!! This is hands down, the best video on transistors I've come across.
I have just watched 5 videos on this subject and ours is by far the best! Well done !
Excellent presentation and production on this video! You have taken a big step up with this one!
Thank you so much, I hade one question, and unlike any of the other peeps on the RUclips...you answered it plain and simple without giant math fractions
I’ve been crawling through the RUclips for 2 days
Yeah, this video is pretty inaccurate. I'm guessing that "Electronoobs" doesn't really know anything substantial about this topic, because he completely misses out on the key differences between these devices. So, allow me:
BJT:
- CHEAP
- Robust against static discharge which makes it very popular
- High voltage capabilities (typ. 40-1000V)
- Best low noise performance when used as a linear amplifier
- When used as a saturating switch, poor turn-off behavior which limits the switching frequency to usually 20A) because the saturation voltage is roughly constant (usually .2-.5V), but...
- Requires a high-current output control driver which makes it unpopular for high current applications
- Current can only flow 1 way in the ON state, Collector->Emitter
MOSFET:
- Medium Cost
- Extremely fragile to destruction by static discharge
- Medium voltages (typ. 20-400V)
- Poor performance in linear amplifiers (nonlinear behavior, high noise)
- Extremely fast switching, easily up to 20MHz with high-power loads (and the new GaN FETs promise to be even faster)
- Efficient for low-medium currents since it behaves like a low-valued resistor
- Easy to drive since the gate is an open-circuit
- Current can flow both ways through the device in the ON state
IGBT (BJT with MOSFET gate):
- High Cost
- Fragile to destruction by static discharge (but usually less so compared to MOSFETs)
- Very high voltage, up to 4000V
- nobody uses these in linear amplifiers because it would be pointless
- switching behavior is similar to BJT, but usually slower (Emitter
So, the TLDR; is that you use BJTs for building robust interfaces since they usually don't need ESD protection, you use MOSFETs for low-medium current switches, and for really high-current switches you use IGBTs. The distinction between MOSFETs and IGBTs is basically on the basis of efficiency - the heat generated in a MOSFET increases as I^2 since it behaves like a resistor, whereas in a IGBT it increases more like Log[I]. You will have to do some math to figure out which transistor to use on a case-by-case basis.
Hope this is more helpful to people than the video was.
Colin Marcus this is exactly what I needed, thank you so much!!
@Chris Russell - UJTs are very rare... in fact I have never seen one used in a design. To my knowledge there are only 1-2 components on the market at this point, so they are pretty much extinct.
@Colin,
Thank you for the information, but you're an idiot though, have more respect when writing. Your comments about the video are disrespectful and don't appreciate the work done for the people. Otherwise, thanks for the useful info. Idiot learn some manners. Sorry had to add the last line 🤷
So where is your video? You know this is RUclips channel. All you did is gave more information that noob doesn’t understand anyway. Why criticize someone’s work which was completely adequate for a noob? So no, your information wasn’t more helpful to a noob. It was useless. But still, thanks for effort. Thanks for sharing. Thanks for spending time to help someone.
@@Traderhood some people think they were born knowing it all it is a character trait, nothing to get one's feathers all ruffled, there's always somoene above and below 😒
I'd love to see these used in example projects. Like a full project video for each type, maybe even a few different applications.
The block graph was a perfect visual. thanks for this explanation!
Excellent video with great graphics that explain the voltage, current and frequency combination of the three different type of chips.
After all these years, finally your video explained me where to use which, thanx
That 3D block diagram of voltage, current, and frequency brought it all together. Thank you.
I must say, this is the best video on transistors. Thank you for clearing the air!
I've learnt so much from this channel. Thank you!
What a great video. I loved the idea of the 3D graph @ 6:22, and the graph itself of course!
Sir, your voice is so sweet.Thank you very much for giving us so precious knowledge.
thank you for every information you give people!
THANK YOU! Awesome! A few more practical examples would have been nice though, explaining in a little more detail when to use which type. Nevertheless, superb video!
Seriously one of the best explanations I’ve heard, and I’ve heard MANY
Great beginner video. I would love to see you use each of these in 3 different circuits showing 3 real-world examples of their uses.
Thanks. Today is my exam. You saved me! ❤️
Just great, I am studying engineering and its very important to understand that BJT can handle high voltages but low currents because when you try to use them with high currents the Saturation Voltage between Collector and Emitter increases and it implies higher power losses. MOSFETS can handle high currents once you apply around 12V to its Gate, but they have no reverse polarity protection and also can't handle high voltages, IGBTs are great for both purposes high voltage and high current but a disadvantage is that the C-E saturation voltage when you handle high currents increases and brings again higher power losses, well, perfection doesn't exist, right?
Thank you. It's so easy to understand. I want to travel back in time to my EE years and show this video to my Past self.
Parabéns pela explicação e aplicação, 👍Muito bom
Great introduction. Thanks a lot for your work!
Well simplified and explained for such electricity raw material beginners like myself, thanks mate and keep up.
I'm a beginner , but I don't understand , I'll seek for another simple explainations videos
Thank goodness I found this video, been looking for this brief explanation and comparison about transistors. Very nice. :-)

It is a very good short video. Thanks a lot!
Amazing video! Could have really used this back in Eng. I really liked the 3D graph to visualize the current and voltage ratings.
real it is inclusive knowledge about transistor . i am delighted at your presentation n methodology . Many thanks ! Electronoobs
6:26 for my future reference on project DIY. THANK YOU SO MUCH 🙏🙏🙏🙏
Its very usefull. Thanks
I hope you will make this kind o f video for the future.
@@ezion67 i know. But something like this is very important for youtube comunity
I am so glad you are so good and you speak perfect English. By next spring, you will be at 1M. I am 59 and no one has explained these devices as well as you have. Thanks, Noob. (I just added that (Noob) to the (my) Dictionary. Keep up the good work and be safe.
I finally understand transistors now thank you so much!!
I really love the Italian like English accent, btw you earned a new subscriber
I believe he is from Spain
Great video. So much valuable info in this video. Thanks.
excelente, no entiendo el ingles pero el apoyo gráfico compenso por mucho, tanks you for you work
Thank you, thank you. Love this stuff!
Loved your explanation of the different components thanks for sharing, new subscriber.
Awesome presentation
Loved it...
I have at home a igbt module with one defective igbt (the module have 2 for each motor phase), and I was thinking about using it to make a guitar amplifier. Since the module still have 5 working igbts and they are kinda high wattage, I could use the same module to make the amps power source, preamp and power amp stages.
Thanks, man. I DID need it broken down that simply...
Low ON losses will depend on the load current. Because some Mosfets have very low Rdson and the Collector emitter volt drop of and Igbt is around 1.2 Volts. So you should also calculate the conduction losses before deciding on Mosfet or igbt
Really interesting! Thanks a lot! 😃
And that's why quadcopter's escs use mosfets. 😃
Great information summery. Thank u
Can you show with examples on breadboard for each types
Haaaay malayaliiiiii😱😱😂😂
You just made my day 👏👏
Awesome video man thank you for your time 👍🧡
Yet another great video 👍
Perfect brief explanation. Thanks.
MOSFET is fine with high voltage as well. IRF840 can go up to 500V and I own few IXTF1N450 MOSFETs with a rating of 4500V and 0.9A (continuous Vds and Ids. They are incredibly expensive).
from my internship at a company that designed and built power converters , a rule of thumb I came across is that around 1000V mosfets begin to lose out to IGBTS due to the tradeoff between voltage rating/impedance. ......sounds like a incredibly specialized mosfet. very cool! (and very expensive ;-) ).
@@km5405 True. The resistance of this MOSFET is very large compared to IGBTs with similar voltage rating. The main advantage is higher on-frequency.
@Mdmchannel Yes, 4500V. It's much larger then regular MOSFETs
@Mdmchannel www.mouser.com/ProductDetail/IXYS/IXTF1N450?qs=wUaLziKAieVmbFKN0j%2FKRQ==
@Mdmchannel
IXTF1N450(4500V0.9A-MOSFET)
IXBT12N300(3000V12A-IGBT)
FGA25N120ANTDTU(1200V25A-IGBT)
IXTA-H1N200P3-HV(2000V1A-MOSFET)
IXTF02N450(4500V0.2A-MOSFET)
FGA25N120ANTDTU(1200V25A-IGBT)
The last IGBT is used in some induction cooker - you can find some costing only few dollars on amazon (not sure about quality but I guess it's fine).
These are what I got. I'm not an expert.
Think about the current / voltage / switching time / leakage current you want.
High voltage MOSFETs general have higher on-resistant. Take that 4500V MOSFET as example, the on-resistant is several hundreds of ohms but offers better switching time.
If you don't care about switching time (for example, operating within 1000 Hz) but need high current, go for IGBTs.
Read datasheets carefully when making your choice.
You can find much more on Mouser website. You have to pay more if buying from Mouser. However, if you buy on Amazon, you risk buying recycled electronic components.
Awesome Video , clear my base on this topic. Thanks
Good video but I was missing a little more about the reading of a datasheet for a transistor,
e.g. what does "Continuous current rating" mean exactly and what is this entry used for?
This is school 👏 EXPLAINED EVERYTHING 😊
Great explanation. I have suscribed to your channel waiting for more videos
Primera vez escucho tu voz en inglés y siento que me vas a hablar en español en cualquier momento 😅. Excelente video por cierto
Very helpful video 👍 Excellent
Excellent video! Very informative!
very good video, everything was clear
Wow. Just wow. Excellent I am a noob and this is just at my level. Perfect for me.
Best explanation I ever seen
Excellent explanation💯
Perfect explanation Master 👍
I would have a question:
- I built several „drivers“ (H-Bridge) for stepper motors. The motors consume about 2A per phase.
I am using Power Mosfets: IRFZ44N, IRF9510, IRF4905, IRF740.
My question would be:
- Do you need protection diode power Mosfets? Looking at the photo of the Mosfet (on the datasheet), the Mosfet has the built-in protection diode. But I'm not sure that is the case. Or if you want to say that ...
If anyone knows, I would be very grateful ...
thanks and greetings to all ✋
very informative video. Can you tell us which software you are using for your presentation? It's awesome.
انت رائع 💓استمر
Great explanation👌
Its crystal clear. Thank you.
Hey which software do you use to make those animations. They are really cool and I want to try them out. Btw awesome video
How do you made this awesome graphics/animations?
A great video, but @ 6:25 IGBTs are more frequently found in welding equipment as the welding current control semiconductor device, second to that is usually thyristors.
Excellent information presented clearly. Could I ask what you use for your 3d animations?
Probably blender
Good animations! I like it! :)
Nice handle the subject very clearly welcome
Tq
thank you at all. It's real usefull information
Very informative. Thank you
For amplifiers, your best bet is to go with BJT’s, because they have very high transconductance. On the other hand, MOSFETS are nice because you can easily integrate digital control into analogue elements on the same IC, however, they do have poor transconductance. Over all, BJT’s are nice, but their performance (IE in a emitter coupled pair) is limited by thermal voltage. This is not true with MOSFET’s.
Quick Question? If it's not for the effectiveness and efficiency matter, can you used any one of the three types of the Transistors in any circuit(for any devices)? Just asking what pops up in my head. Thanks to you though. You taught me many things about a Transistor just now.
Thank you sir from Turkmenistan
Nice tutorial!
Great video. How do you make these animations?
thank you man you are the best 😊
Thank you for your great video 🙂☺️
When you say high voltage, low current etc, which voltage and which current do you mean?
Thanks for the video sir .
Hi friend, can we port kk2.15 firmware on Arduino as both share same motion sensor and cpu 328p , I need to complete my bicoptor by August ,
Great video! But.. i will disagree with the frequencies amps and voltages. There are plenty of mosfets working with voltages of 1000v and above, and BGTs capable of handling hundreds of amps. Also lots of them easily handle megahertz even gigahertz frequency region.
worvtube not good for rf application if the gate capasitance is high.
@@emppu-tech6065 Sure thing. You can't have all of the good stuff at the same time unfortunately.
Well explained 👌
Such a great video!
A very well done video, I especially like the 3D performance/Applications chart. I'd be curious to know what you used to make that.
