Default Diode identification?

Thus spake Palindr~ğme:

Any chance of reverse-engineering the bit of the circuit it is used in,
and
producing a bit of a circuit diagram?


Not very good at this... just a component-test monkey (c:

But it (and its partner) seems to be across a c.t. winding of the SMPS
transformer. Electrolytic filter caps "downstream" from these are rated at
25v.

There are a dozen more of this type of diode in this SMPS, across other
trans. windings.

This is a multiple-voltage ps inside a 240v ac motor controller in a
Japanese
printing press.

If it's on the secondary side, it will not be a 'normal' 1A diode. It will
be a high speed Schottky type. If you try to use a standard silicon
rectifier diode, it will run very hot and fail, in short order.
