...because you'll need at least 3 per leg and for a full bridge this will
make 12 diodes. Easier to look for TV replacement diodes

Subject: Re: [Amps] PIV requirement for identical, individual diodes used in
a bridge rectifier configuration?
I think you need more than 2 KV. maybe around 9 KV but I stink at
remembering the tech. details because I can't remember what I had for lunch
yesterday. But why don't you just use 6A10s and be done with it. No
surprises--and they're around 50 cents each.

4KV (due to two reverse-biased diodes in series), or if not, how do I
determine the appropriate diode rating requirement?
