Thanks for covering this. Your timing is perfect! I was just watching " Mr. Carlson's Lab" on building a curve tracer to work with an old analogue oscilloscope. It uses an oscillator circuit to do this that you can build from a handful of parts. I rebuilt a record player tube amp with two 50C5's and a 12AX7 filaments in series.(50+50+12 volts- no transformer) The current for all the heaters is the same, but the 12AX7 went to to 22 volts while the 50C5's were warming up. 12AX7's and some other small European tubes are bad about heater "flash" during warm up. I converted the amp to dc for the filaments and used a 15 volt zener across the filaments of the 12AX7 to protect it. I could have used this diode instead of redesigning a DC filament circuit. AGAIN I learn from my mistakes and your videos! Thank you sir! Best regards!
Very informative videos on how TVS diode work (485, 486 & 495). I came across these videos after doing some research recently on ESD after having great difficulty in diagnosing an output fault in a dual voltage power supply board that is suppose to put out 12v & 24v but only has 24v output after a lightning strike. The board was installed outside, inside a metal box, along with a control board and several circuit breakers, near a salt water pool. After days of scouring the board, testing numerous components (removed) and coming up empty & extremely frustrated, it struck me @ 3am (sleep?)😵💫😵 that this had to be caused by ESD. 🤔There was no obvious damage. I have yet to figure out where the fault is😡 by I'm leaning in the direction of a control IC as I would think they would be the most susceptible to static damage vs the other components and they are pretty much all that is left on the list.🥱 It would be helpful to see a sequel to these 2 videos showing how a pcb (power supply board) can be protected and how to add protection into an existing pcb using smd TVS diodes.🤓 I am an addict to your power supply videos, I watch them over & over. Thank you so much for taking the time to share your amazing electronics knowledge with us. It really is appreciated.
Thanks for this informative video 👍 How do you know if it is unidirectional or bidirectional? In an example of high-frequency ignition of a TIG welding system, sensitive devices are affected. Do you choose unidirectional or bidirectional protection? According to the data sheets, the starting pulse should be up to 15kV. Where does the protection have to be placed? At one, or rather at several points in the circuit? This problem prompted me to find out more about protection, especially since an iPhone has no failures, while a Raspberry Pi, for example, constantly fails as soon as the arc on the TIG system is ignited using high frequency. I would be very happy to receive information, or at least tips on where I can find out more about it.
i provided the test result for a good TVS. if TVS is damaged, it will short circuit of it becomes open junction it is just to explain the function of the TVS because it was a question of my viewer
ma shaa Allah
it is really best explanation on bidirectional tvs. thanks for sharing your excellent work
thanks a lot

Superb video 👍👍👍👍
Many many thanks dear sister
If I connect the cathodes of two TVS unidirectional diodes with the same values, will it be a bidirectional TVS diode?
W salam nice sharing 👍
best regards and special thanks
humaira sis mein ne apney sabhi chnls se aap ko pehley se sub kia hua he.
aap apni construction work wali video mere six channels ke comments dekh sakti hein
So informative excilent job bro 😊
best regards and special thanks
Nice
Thumbs up done
i am thankful
Nice 👍
thanks a lot dear friend
I need some information about smd bidirectional tvs diodes which use in VFD. Do you know any types used mostly?
1.5SMC series
p6SMB series
SMDJ series
and many other
How do I identify a bad bidirectional tvs diode?
How do you test if the bi-directional diode is still okay?
i provided the test result for a good TVS. if TVS is damaged, it will short circuit of it becomes open junction
it is just to explain the function of the TVS because it was a question of my viewer
@@HaseebElectronics Yes but how can you test to see if it is working normal. If it is open how would you know?
How to chake bidirectional diode
Hi . Is it an 1.5 KE 36 CA - E3 TVS is BIPOLAR ? Thank's in advance .
when it have suffix "CA" it means it is Bidirectional TVS
