AUIRFB8409

Infineon Technologies · MOSFETs · TO-220AB

AUIRFB8409 from Infineon Technologies, in a TO-220AB. 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 HEXFET; the gate-to-source voltage is rated at ±20V (VGS).
2 D passive Drain terminal; the drain-to-source breakdown voltage is 40V (VDSS) and the package-limited continuous drain current is 195A.
3 S passive Source terminal; the datasheet specifies the continuous source (body diode) current as IS and the pulsed source current as ISM.
