STN442D

STANSON Tech · MOSFETs · TO-252

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℃.
