STB20NM50T4 from STMicroelectronics, in a TO-263. 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 N-channel MOSFET; gate-source voltage is rated at ±30 V (VGS, Table 1). |
| 2 | D | passive | Drain of the N-channel MOSFET; drain-source voltage is rated at 500 V (VDS, Table 1). |
| 3 | S | passive | Source of the N-channel MOSFET; continuous drain current is rated at 20 A at TC = 25 °C (ID, Table 1). |
