RS9N50F

REASUNOS · MOSFETs · TO-220F

RS9N50F from REASUNOS, in a TO-220F. 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 terminal of the N-channel MOSFET, with gate-to-source voltage limited to ±30 V and a threshold voltage of 2 V to 4 V.
2 D passive Drain terminal, rated for 500 V drain-to-source voltage and 9 A continuous drain current at TC=25℃ (34 A pulsed).
3 S passive Source terminal, with continuous source (body diode) current rated up to 9 A and pulsed 34 A.
