A retired EE here... This presentation is an excellent coverage of heat sinking! My last redesign effort for the US Government was to increase the upper temperature range of operation of a SCRAM breaker. While I was required to keep the circuit topology the same, I had to reevaluate every component for extended temperature operation and ended up replacing numerous components to achieve the stated requirements. It required a bit of effort, but was achievable! Please keep up the good work, I really enjoy your videos. Now that I'm retired, I'm able to once again enjoy my hobby of electronics verses the job of electronics. I wish I was in your Utica, NY area to attend some of your classroom sessions, but its a long commute from the greater Philly PA area.
Thanks for the kind words, Joseph. Yes, Philly is a ways off from the foothills of the Adirondack Mountains, but as consolation, I've been told that Philly is one of the few places where you can get something that Utica is famous for, namely, our delicious tomato pie! (and to anyone reading this, if you're picturing something like cherry pie but with tomatoes instead, you couldn't be more wrong) Now I'm hungry....
@@ElectronicswithProfessorFiore Yes, tomato pie! I grew up eating tomato pie for lunch every Friday as a kid in Catholic school. And now, I often eat it on other days of the week! My last visit to Utica, several years ago I had a hot italian sausage parm sandwich that I'm still dreaming about!
It's nice to finally catch up with you. I have been ardently watching your series of videos, most of which you posted some 4 years ago. Happy to see that you are still prolific. May I commend you on not only the magnificent content, but the manner in which you deliver. Very personable and light hearted, but you get the point across so well. Cheers AB.
3:01 Does LTSpice take the delayed effect (due to the temperature time constant) into account into the electrical behaviour of the transistor (thermal self-modulation)? Worse, if we include the heatsink model (with additional temperature time constants) into the circuit? Or is the transistor temperature only an output of the electrical behaviour simulation? Is it easy to check and verify this one way or another?

What a great tutorial ! Thank you Professor Fiore.
Thank you Professor, maybe you could clarify thermal impedance as well in a follow up video sometime?

I have not used LTSpice to any great depth, and do not know the extent to which LTSpice will consider any of those issues. Sorry.
@@ElectronicswithProfessorFiore Thank you very much for replying. If I find an answer, I will post back.
2:17I don't get it: why does the power display a double hump when current and voltage crests perfectly synchronise?
We're calculating Pd of the transistor, not Pload. Take the product of Ic and Vce (not Vload).
@@ElectronicswithProfessorFiore I didn't realise! Thank you very much for your reply .
