IRFZ44NS-HXY

HXY MOSFET · MOSFETs · TO-263

IRFZ44NS-HXY from HXY MOSFET, in a TO-263. 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; the datasheet limits gate-source voltage to ±20 V (VGS), and the device is rated for operation with gate voltages as low as 4.5 V.
2 D passive Drain terminal; drain-source voltage is rated at 55 V (VDS) and continuous drain current at 49 A (35 A at TC = 100°C).
3 S passive Source terminal; continuous source current is rated at 49 A, with a pulsed source current of 160 A.
