C3M0021120K from Wolfspeed, 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. 1200 V max drain-source voltage (V_DS_max). Continuous drain current 100 A at T_C=25°C (74 A at T_C=100°C). Electrically connected to the tab (pin 5) for heatsinking. R_DS(on) typ 21 mΩ at V_GS=15 V, I_D=50 A. |
| 2 | S | passive | Power Source (main power current path). Carries the drain-source current back to the load; typically bonded to the high-current source terminal. Should not be used as the gate-driver return in this 4-lead package (use pin 3 for that). |
| 3 | SS | passive | Driver Source (Kelvin source). Low-inductance sense connection to the source used as the gate-driver return reference to eliminate common-source inductance and reduce switching losses / gate ringing. |
| 4 | G | input | Gate. Recommended drive V_GS = -4 V / +15 V (V_GS_max dynamic -8/+19 V, static -4/+15 V). Gate threshold V_GS(th) typ 2.5 V. Total gate charge Q_g typ 162 nC; internal gate resistance R_G(int) typ 3.3 Ω. |
| 5 | D | passive | Drain (metal tab). Same net as pin 1; provides the thermal / mechanical mounting surface (R_θJC typ 0.32 °C/W). Must be treated as electrically live at drain potential (up to 1200 V). |
