Normally you'd need a HV curve tracer or a hipot tester or some sort of
current-limited HV tester to determine that. CSdc made a lot of microwave
oven diodes as well as other stuff and the P/Ns were mostly OEM custom
"unique" P/Ns that weren't in any catalog, but were traceable back to a
customer and application.
I'd suggest measuring Vf from a low voltage source but while that will tell
you approximately how many junctions are in series, it won't tell you the
breakdown voltage of those junctions.
Another trick I've used on these items is to bring them to my dentist's
office after hours and have them X-rayed to see what's inside. If you see
ten large diodes strung in series, you can probably assume each is at least
600 PRV and you'd have a 6kV or better stack. No guarantees, but "looking
inside" can be revealing, and the dental X-ray is usually powerful enough to
take a shot.

Subject: [Amps] Help IDing DSdc diodes
I've got a set of four epoxy block diodes that I would like to use in
my next home brew amplifier power supply. The problem is that the
company that made them, CSdc (Conditioning Semiconductor Devices
Corporation) was bought up back in the 80's and I can't find anything
on the web about the value of the devices. I would sure like to know
what C67-6225A by CSdc is. They are 1 inch square by 5.5 inches long
black epoxy blocks. Any help would be greatly appreciated.
Thanks,
