Is there any way one can make use of IGBT power module like EUPEC FZ1200R12KL4C, its capable of 1200A and 7.8KW.
I have one and was wondering if one could use it to swap the output stage of class D amplifier ??? Target 2KW subwoofer amp.???

No, there's no way to adopt such IGBT's for amp output stage... reason being - these bricks are way too slow.
And I'm guessing, U don't have much experience ? 7.8k is the maximum dissipated power at 25deg.C. Not the abilities of transferring the power. If such bricks w'd be fast enough, then single brick (half bridge) w'd be capable of doing dozens of kW.

the specs look quite interesting actually! very low total gate charge, switching times seem to be very fast, but what they don't list the On Resistance. In this case would be Rec (Rds for a mosfet) If the Rec is high, you will suffer a lot of loss and hence a lot of heat during the on transitions.
IGBT's i think were designed for switchers and inverter type applications.

...is it not what the Class D does ?
ok, ok, I know what U meant
