Will these IGBs be good enough?

I'm making a small DRSSTC and I was browsing through IGBTs and I came across these -
APT65GP60L2DQ2G

These seem to be better, but I'm not sure if they're fast enough -
APT102GA60L

My question is, is the second one fast enough, if not, will the first one work?

They will be ran at around 80kHz, and i'll be pushing about 300-400 amps...

Both should switch at 80Khz with no problem. Look at the rise and fall times in the data sheet next time, that is all the info you need to know for switching.

Currentkills91,
they've got about the same delay; rise and fall time as the APT50GP60 I was enquiring about, which is given for 200Khz operation. About the same price as these on digikey too! What frequency are you planning on operating?
Tell us how these fare, it's about time, we had more IGBT references on HvWiki for DRSSTC use...
