HFDD050N03B

HXY MOSFET · MOSFETs · TO-252-2

HFDD050N03B from HXY MOSFET, in a TO-252-2. 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 of the N-channel MOSFET, with gate-source voltage rated ±20 V and a gate threshold of 1.0 V min to 2.5 V max at 250 µA.
2 D passive Drain of the N-channel MOSFET, rated for 30 V drain-source voltage and 100 A continuous drain current at TC=25°C.
3 S passive Source of the N-channel MOSFET, with a body-diode continuous source current of 80 A max.
