FQA9N90C-F109

onsemi · MOSFETs · TO-3PN

FQA9N90C-F109 from onsemi, in a TO-3PN. 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; gate-source voltage is rated at ±30 V maximum with a gate threshold of 3.0 V to 5.0 V at VDS = VGS, ID = 250 µA.
2 D passive Drain terminal; drain-source voltage is rated at 900 V with a continuous drain current of 9.0 A at TC = 25°C.
3 S passive Source terminal; maximum continuous drain-source diode forward current is 9.0 A.
