fake or real ?

Sorry this isn't entirely about class d amps but you are far more experienced with parts like these.

Hello. I recently bought a few IRFP 360LC. The store I bought them from says they are made by International rectifier but the logo certainly doesn't look like the IR logo from other parts.
I searched for the companies that manufacture semiconductors but couldn't find this logo. Did I buy some fakes ? Did IR change their logo ?
Here is a picture next to some other components to show the diffrent logos :

I don't know if your transistors are fakes, but I believe Vishay now makes the IRFP360LC. I don't know how they mark them, but you might want to look into it.

I think it can stand the power what it was made for.
