BY255 should be a suitable building block rated 1300V PIV 3A. Use equalizing resistors in parallell with each diode, typical values used are 470...820kohm. Only controlled avalanche diodes can be ser

Hi Paul. If I could locate some BY1800 or BY2000 (1800v & 2000 V) that would be better, but again have not found a stockist, the BY255 were from Germany. Ken M0KHW Ok Ken Further I would not worry as

Hello Everyone. Thanks for the replies, I have some BY255's which are rated at 1300v at 1A, the input to the diode stack is about 2.3KV peak, and was planning to use two BY255s in series in each of t

Ok Ken Further I would not worry as much regarding the voltage rating of the equalizing resistors. Use physically large units with an adequate power rating (U^2 / R) and they will probably be fine. A
