WGD20N03S from Wild Goose, in a TO-252. 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 N-channel MOSFET, rated for a gate-source voltage of ±20 V (VGSS). |
| 2 | Drain | passive | Drain terminal, rated for a 30 V drain-source voltage (VDSS) and 20 A continuous drain current at TC=25℃. |
| 3 | Source | passive | Source terminal, the reference for the gate-source rating (±20 V) and the drain current ratings, with 60 A pulsed drain current (IDM). |
