Title: Avalanching Transistors
Post by: Grumpy on 2010.09.22, 20:28:30
Transistors can be operated in avlanche mode to produce short HV pulses:

After trying to use 2N5551's for a long time, I gave up.

They are too hard for me to trigger, needing a trigger pulse of at least 10v and rise time less than 10ns.

All Zetex avalanche transistors and 2N3904's are easy to trigger.

I have a few HV transistors that I have not tried yet.
