WTM20N65CP from WPMtek(Wei Pan Microelectronics), in a TO-220. 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; controls the channel with a gate-source voltage limit of ±30 V and a threshold of 2.5 V to 4.5 V. |
| 2 | D | passive | Drain (also connected to the mounting tab); handles 650 V drain-source voltage and 20 A continuous drain current at TC = 25℃. |
| 3 | S | passive | Source; the current return terminal, with a continuous body-diode forward current of 20 A. |
