Hi,
I recuperated a lot of semiconductors but I now face the identification of these item, principally mosfet and igbt. How can I identify the one from the other with e.g. a dmm ?
Kind regards,

You might look into the component testers comming from China. They can be bought from about $ 9 to $ 20.

The design was done in Europe, if I am not mistaken, and shared online - and the Chinese are simply flooding the market with it with the help of their government making shipping worldwide essentially free (heavily subsidized) to weaken foreign suppliers/designers like the good folks in the US and Europe.
And, yes, I bought three for my staff, they do work well. Sigh, participating in the drive to the bottom...

For a first pass, Mosfets have a parasitic internal diode from drain to source. IGBTs don't, unless an extra part is added internally.
You really should decipher the part markings, for real information on the part, before redeploying it.

The basic IGBT is an n-channel MOSFET with a PNP emitter follower hanging from the drain, so that test should clear things up.
