Hi! I am working with four pin mosfets (C3M0030090K). (Datasheet here- **broken link removed**) I want to drive them in one leg configuration like this- I am getting the pulse at load resistance of the circuit. However, I am also getting similar pulse at gate of M1(which I shouldn't). I am using ACPL 337J gate driver. Here is the schematic- .

Library for 4 pin mosfet- View attachment C3M0030090K.txt

Please suggest any edits in the circuit so that the circuit might work as desired.

I guess you did not measure voltage between gate and source of M1 as you should.

I am getting the pulse at load resistance of the circuit.
So why "can't run"?
