Unknown component...

This is in an elma antimag demagnetizer.
I think it is just a pair of diodes. But I'd like to be sure. It has 3 terminals and measures about 5Mohm both forward and reverse across each supposed diode.

looks like some kind of rectum frier to me .
Have you a diode test setting on your multimeter? if so you should be able to read the forward voltage and check each diode.

I do, but it is effectively open circuit.
(ie, I think it is dead). Drawing out the circuit to make sure diodes make sense.
(not some odd scr or other complexity)

Looks very similar to this full bridge rectum frier. But perhaps just a half bridge with 2 diodes.

It's a half-wave rectifier.
