**Wayon** · MOSFETs · TO-220F

WML25N80M3 from Wayon, 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 | G | input | Gate terminal, with a maximum gate-source voltage of ±30 V and a gate threshold voltage of 2.5 V min to 4.5 V max at VDS=VGS, ID=0.25 mA. |
| 2 | D | passive | Drain terminal, rated for 800 V drain-source voltage, 21 A continuous drain current at TC=25°C and 78 A pulsed drain current. |
| 3 | S | passive | Source terminal, which also carries the body diode with a continuous forward current of 21 A and a pulsed current of 78 A. |
