# YGW40N120T3

**luxin-semi** · IGBTs · TO-247

YGW40N120T3 from luxin-semi, in a TO-247. 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 drive terminal of the IGBT, rated for ±20 V continuous and ±30 V transient gate-emitter voltage. |
| 2 | C | passive | Collector terminal of the IGBT, rated for 1200 V collector-emitter voltage and 80 A DC current at TC = 25°C (40 A at TC = 100°C). |
| 3 | E | passive | Emitter terminal of the IGBT, the reference for the collector-emitter and gate-emitter voltage ratings. |
