**WPMtek(Wei Pan Microelectronics)** · MOSFETs · TO-220F

WTM20N65AF from WPMtek(Wei Pan Microelectronics), 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 an absolute maximum gate-source voltage of ±30 V and a threshold voltage of 2.5 V to 4.5 V at VDS = VGS, ID = 0.25 mA. |
| 2 | D | passive | Drain terminal rated for 650 V drain-source voltage and 20 A continuous drain current at TC = 25°C (12 A at 100°C), with 57 A pulsed. |
| 3 | S | passive | Source terminal that carries the continuous drain current up to 20 A at TC = 25°C and the body-diode forward current up to 20 A. |
