FDD8447L-HXY

HXY MOSFET · MOSFETs · TO-252-2L

FDD8447L-HXY from HXY MOSFET, in a TO-252-2L. 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, rated for VGS of ±20 V and specified for operation with gate voltages as low as 4.5 V, with VGS(th) of 1.2 to 2.0 V.
2 D passive Drain terminal, rated for a drain-source voltage of 40 V and a continuous drain current of 60 A at TC=25℃.
3 S passive Source terminal, the reference for VGS and the source-drain body diode, which has a forward current rating of 68 A.
