Autotek Mean Machine 4000 watt gate driver

[barber02]

I have a Mean Machine 4000 that has some defaced gate drivers on the driver board that I can’t ID. They are on the wide side at 5mm wide. Just curious if anyone out there would happen to know what these are.

Thanks,
David

Wow. Thanks. That was fast.

Hi barber

i have the same amp, but i accidentally cut off the rectifiers.

i took them to the milling machine and managed to mill off a slight edge of the silicon just enough for me to get a solder tab and then soldered on some jumper legs from another to-247 part but ideally i would like to replace them. the map works fine now and rails build properly.

any idea where i could get some?
