This is an old video I released on Elliot’s Extras back in September 2023. It didn’t get a write up on the blog at the time, so just doing that now. In this video, which was the first ever video for Elliot’s Extras, my second channel, I organise some of my diodes from AliExpress. This is a really long and really boring video, a perfect fit for the first Elliot’s Extras video. :)

The DANGERS of Inductor Back EMF

Watched this one today: EEVblog 1409 – The DANGERS of Inductor Back EMF.

I learned about back EMF, freewheeling, snubber, flyback, or clamping diodes…

In this video I also learned that BPJ transistors have a storage time, or switch off time, in the order of microseconds, e.g. 5 μs. That probably explains what I saw when I tried to measure the frequency response of my DTL OR GATE.
