I am new to IGBTs. I want to experiment with them. I got this older IGBT but unfortunately have no data on it (and all the data I find on the web is fake by resellers.)

How do I know which is gate, collector, and emitter?

Going by the schematic on the side, this is not an IGBT. It's two diodes. One source I can find corroborates this, calling it a "dual rectifier module", but it's pretty hard to find information on this part in general, for some reason.

So there is no collector, gate, or emitter. Terminal 1 is the common cathode of both diodes, and terminals 2 and 3 are their anodes.
