STP12NM50 from STMicroelectronics, 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 | Gate | input | Gate control terminal with ±30 V maximum gate-source voltage for controlling MOSFET channel conduction. |
| 2 | Drain | output | Drain terminal rated for 500 V maximum drain-source voltage and 12 A continuous current at 25°C, 500 V breakdown voltage. |
| 3 | Source | power_in | Source terminal providing return current path and voltage reference point, typically connected to ground. |
