[Premium-Rx] OT - Doorknob Rectifier ratings

[Henry Kolesnik]

I've seen them in the past and had some.  IIRC they can be stacked by 
screwing them together.   Very little info was available since I they were 
probably OEMd.  Tthey were for very high current applications and didn't 
have that much piv rating.  If you don't get any info and you have some 
spares you could apply voltage and see  how high they'll go before they fail 
and then derate.
