My experience too with other diodes. It's a hobby so I never cared to track it down and quantify but I suspect there are some really high voltage spikes that just break down the SS diodes over a relatively short period of time. Once that happens they just become shorts.
The safety margin needs to be much higher than simple calculations would predict. I was blowing 1200 V PIV parts on a ~ 450 DC B+ supply.
