OSD12N50

OSEN · MOSFETs · TO-252

OSD12N50 from OSEN, 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 Gate input Gate control input; gate-source voltage is rated ±30 V continuous with a 2.0 to 4.0 V threshold at ID=250 µA.
2 Drain passive Drain terminal; drain-source voltage is rated 500 V with 12 A continuous and 48 A pulsed drain current.
3 Source passive Source terminal; the body diode carries up to 12 A continuous forward current.
