C3M0032120K from Wolfspeed, in a TO-247-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	Drain	passive	Drain (also connected to the TAB); VDS max 1200 V, continuous ID 63 A at TC = 25 °C and 48 A at TC = 100 °C.
2	Power Source	passive	Power source pin carrying the main load current; 8 mm creepage distance between drain and source.
3	Driver Source	passive	Separate driver source (Kelvin source) pin for the gate drive return, which reduces switching losses and minimizes gate ringing.
4	Gate	input	Gate input; VGS static -4/+15 V, dynamic -8/+19 V (AC, f >1 Hz), with internal gate resistance of 1.7 Ω typical.
