STP12NK30Z from STMicroelectronics, in a TO-220-3. 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; VGS rated ±30 V max, with built-in back-to-back Zener diodes to the source for ESD protection (3000 V HBM) and threshold of 3 to 4.5 V at ID = 50 µA. |
| 2 | D | passive | Drain; VDS rated 300 V max, continuous current 9 A at TC = 25°C (36 A pulsed), also connected to the mounting tab. |
| 3 | S | passive | Source; main current return terminal of the MOSFET, with a body diode to the drain rated 9 A continuous (ISD). |
