I have tested diodes with a 200piv rating that measured >700v. I have also tested "1000piv" diodes that measured 900v. This is the reason why I like to test components.
No, but the only practical way to limit reverse current to a safe value is to use more total piv than exists in the circuit. For example, in the current project, the actual piv per leg should c. 9900v. I used 14, 1000v-rated 1N5408 diodes per leg that measured c. 1300piv each on a high-pot tester. This will give a safety factor of c. 8000v. Richard L.
