I need specs. (voltage and current) on a three-phase bridge.It is an I.R. 60 MT 120 K
I have tried the International Rectifier pages that I could find and so far, no dice. I have also tried the local suppliers to no avail.
Thanks.

Is that a large unit from a lamp supply, Rick? If it's a tiny thing for something else then the following is nonsense.
From the usual way IR numbers diodes - which may not apply to bridges - it may be 600V PIV and 120A. If that current makes any sense - seems like about right for a 3K lamp - then 600/120 may well be right.
We use 600V PIV diodes and even 800V as replacements even though OEM parts are often 400V or less for smaller rectifiers. The higher PIV parts cost about the same and it doesn't hurt anything.
