**Wild Goose** · MOSFETs · TO-252

WGD4N65SE 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 | G | input | Gate of the 650 V N-channel MOSFET; the datasheet specifies gate-body leakage with VGS = ±30 V and a gate threshold (VGS(TH)) of 2 V to 4 V at ID = 250 µA. |
| 2 | D | passive | Drain of the MOSFET (also the tab), rated for a drain-source breakdown voltage BVDSS of 650 V minimum and a drain current ID of 4.0 A at Tj = 25 ℃. |
| 3 | S | passive | Source of the MOSFET, the reference terminal for VGS and VDS, with a maximum body-diode forward current IS of 4 A. |
