09:00 I thought only TVS was used to clamp down static electricity? Can a regular pair of Zener do it aswell, what are the differences of when to use Zener and TVS?

[@ibissaa9695]

I have been scouring the internet and one of the best explanations I have seen for having a series resister. HOWEVER, I have also been looking desperately for an answer to WHY the voltage is constant across the diode? I have read and viewed every info possible including going deep into the science of Zener diodes but no one has explained the WHY. One of the reasons mentioned (including in this video) is that the diode regulates its internal resistance to maintain the voltage. How and Why does that occur? Could you please explain?

[@dumbluck6180]

Here's my best guess. I think it has to do with the "saturation" process. Once the "avalanche" threshold voltage is reached, a set number of electrons can physically move across the junction. If you can't push more electrons across the junction, the voltage on the other side remains constant. Am I right? IDK!

8:00 don’t op amps have low output impedance

[@ricksampson6780]

This is not always the case, may I ask if you have any professional experience in the industry?
