Can you double check that part number? I'm not
having luck finding it.
Yup, that's how it's listed in the schematics. It's part of the crowbar
circuit on the DEC 540972800 regulator board.
There are no visible markings on the part itself It's in an exotic (to
me) big three-pin can package.
Here's the relavent bit from the schematics. See Q11:
