Should be, but those FETs don't have a very good spec when compared to the IRFP4368 TO247 package ones I'm using.
The Ixys FET has a max current of 100A (package limited), a max voltage of 60V and an Rdson of 3mohm maximum.
The IRFP4368 has a max current of 195A (package limited), a max voltage of 75V and an Rdson of 1.85mohms maximum.
The only characteristic that's better for the Ixys FET is the junction to heatsink thermal resistance, at 0.23 deg per watt versus 0.53 deg per watt for the IRFP4368. This thermal advantage is partially lost from the higher Rdson though.
The parts I was waiting for have now arrived, so with luck I may get the board up and running later today.
