STN4NF20L from STMicroelectronics, in a SOT-223. 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; gate-source voltage limited to ±20 V absolute maximum, with threshold of 1 V min to 3 V max at ID = 250 µA. |
| 2 | D | passive | Drain (also the tab); VDSS of 200 V, continuous drain current of 1 A at TC = 25 °C, 4 A pulsed. |
| 3 | S | passive | Source; connects to the body diode with 1 A continuous source-drain current. |
