[email protected] Look in the Tek Cross Reference book? page 12-9 has some info on the
152-0502-00 and lesser information on the 152-0397-00.? The text is
searchable.? It may give you a generic replacement.
I thought the information on U1275 might help understand what it does in
the circuit.?? TekWiki has several other valuable references on the same
page.
Bob.

Hi Robert :
It is a very useful information for me to understand the PSU of 7904 !
On the other hand , I am looking for the data sheets for the fast recovery rectifier 152-0502-00 ( MBD5300 ) and 152-0397-00 ( MR880 ). It was because my PSU of 7904 CR1311 and 1312 using replacements having different shut down result at same loading conditions, it is low loading only !
Thanks !
