You need diodes of a PIV of 1600*1.41 volts (2250V) minimum. Of course you
have to take some safety margin into account: on the order of 3000 PIV ...

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?
