OSP40N20

OSEN · MOSFETs · TO-220

OSP40N20 from OSEN, 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 terminal with Gate-Source voltage limited to ±20 V continuous and threshold voltage of 2.0 V to 4.0 V at VDS=VGS, ID=250μA.
2 Drain passive Drain terminal (also the metal tab) rated for 200 V drain-source voltage and 40 A continuous drain current, 160 A pulsed.
3 Source passive Source terminal carrying up to 40 A continuous diode forward current, with a body diode forward voltage of at most 1.4 V at IS=30A.
