STN442D from STANSON Tech, in a TO-252. 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 limit is ±20 V, with a gate threshold of 1 V min to 2.5 V max at VDS=VGS, ID=250 uA. |
| 2 | S | passive | Source; continuous source (body diode) current is 32 A and the source is the MOSFET's low-side terminal. |
| 3 | D | passive | Drain, connected to the exposed tab and the short middle lead; drain-source voltage is rated 60 V and continuous drain current 37.0 A at TA=25℃. |
