SUPSiC · Silicon Carbide Field Effect Transistor (MOSFET) · TO-247-4

GC3M0021120K from SUPSiC, in a TO-247-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 D passive Drain (also connected to the TAB/heat-slug). Blocks up to VDS = 1200 V (VGS = 0 V, ID = 100 μA). Conducts continuous ID = 100 A at TC = 25 °C (74 A at TC = 100 °C) with RDS(on) = 21 mΩ typ. at VGS = 15 V, ID = 50 A.
2 S passive Power Source - main high-current source terminal that carries the drain-source load current back to the bus. Internally the same node as the driver source but bonded separately to isolate the high di/dt path from the gate loop.
3 S_drv passive Driver Source (Kelvin source) - low-inductance sense return for the gate driver. Reference this pin, not the power source, for VGS drive so package/lead inductance in the power source path does not degrade switching. VGSmax dynamic -8/+19 V; static VGSop -4/+15 V.
4 G input Gate - MOS control input. VGS(th) = 1.8/2.5/3.6 V (min/typ/max at VDS = VGS, ID = 17.7 mA). Recommended drive VGS = -4 V/+15 V; internal gate resistance RG(int) ≈ 3.3 Ω; total gate charge Qg ≈ 162 nC at VDS = 800 V.
