FDD8445-HXY

HXY MOSFET · MOSFETs · TO-252-2L

FDD8445-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 of the N-channel MOSFET; the gate-source voltage is rated at ±20 V (absolute maximum).
2 D passive Drain terminal; rated at 40 V drain-source voltage (VDS) with 60 A continuous drain current at TC=25°C (VGS @ 10 V).
3 S passive Source terminal of the N-channel MOSFET; the datasheet gives no separate source-pin limit beyond the device ratings.
