I had to start the video twice, I thought I was hearing things!
I'd probably be more curious if the new TVS was functional. If I took an old one out because I thought it was bad, it hits the can. I'll have to hook one to my HP supply and do a little test.
I'm suitably impressed. My 36V TVS limited right at 36 volts at around 50ma. I guess that one is a good one.
