I have purchased Fuji 2mbi600u2e-060 IGBTs for use in my final design. These are 600A, 600V half bridge modules.
Currently, though, I'm testing with Fuji 2mbi200n-060 which are 200A, 600V modules. I've blown a couple of them up because I was dumb and left too much input inductance. Also, my gate resistors were stupidly small for the 200A modules (I think I was using 3 ohm resistors.)
I have since purchased a big film cap for the input and have minimized loop length as much as possible. Also, I have put 9.1ohm resistors in for the gate resistors. I hope that all of this makes things work a bit better but I've had no time to test it yet.
