# WGF18N50SE

**Wild Goose** · MOSFETs · TO-220F

WGF18N50SE from Wild Goose, in a TO-220F. 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 | Gate | input | Gate terminal of the MOSFET; gate-source voltage is rated at ±30 V (VGSS). |
| 2 | Drain | passive | Drain terminal of the MOSFET; drain-source voltage is rated at 500 V (VDSS) and drain current at 18 A (ID, TC=25℃). |
| 3 | Source | passive | Source terminal of the MOSFET, the reference for the gate-source voltage and drain-source ratings. |
