hey all,
i need help finding SF1600 diodes or similar, is there a way to find an equivelnt part to SF1600 by a different manufacturure instead of Vishay. mouser, digikey and others seem not to have it, but i need 2,000 of the buggers for my college project. it must be a fast, avalanche rated, HV diode.
i use many of these in series for a 22kV pk-pk full wave bridge rectifier, at 100kHz. any help is appreciated.

Try searching NTE for an equivalent. You can also call/email them. I had a similar issue with HFA15tb60 Diodes and was able to find something similar through NTE.

Found this on a digikey parametric search, seems pretty similar:
It has the same 75ns reverse recovery time . I'm not sure how the forward recovery time will impact your project, but at 500ns which is 5% of your 100kHz period it's probably not too bad.
