**STMicroelectronics** · IGBT Transistors / Modules · TO-247-3

STGW40H120F2 from STMicroelectronics, in a TO-247-3. 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 | G | input | Gate terminal of the IGBT; gate-emitter voltage is rated ±20 V (VGE). |
| 2 | C | passive | Collector terminal, also connected to the mounting tab (TAB); collector-emitter voltage is rated 1200 V (VCES) with 80 A continuous collector current at TC = 25 °C. |
| 3 | E | passive | Emitter terminal, the reference for VGE and VCES. |
