2CL2FM High Voltage Diodes 20KV (20,000 Volts) 100mA Axial Lead (10 Pieces)

I configured 4 into a mineral oil covered bridge rectifier to remove AC out of a ZVS flyback circuit. Before I would get 9K volts DC with 4K volts AC on HV probe. First attempt worked, no AC on probe, til I got to 17K volts then dead short; the amps would climb on PS. Second attempt made it to 18K volts. The 100mA rating is great but double in series if you push more than 15-16K through them.I had some 20K 20mA diodes and repeated the process and they held up to 19.5K which is as high as I wanted to push them. Drew an arc and they handled it. So amps isn't the problem, its the voltage rating.If you stay within that limit these are very good. 4 stars for only being able to handle 4/5ths of their voltage rating.

I use in a stack to 160kV with grading capacitors. These work well and make a compact arrangement.
