HYG037N04LR1D

HUAYI · MOSFETs · TO-252-2L

HYG037N04LR1D from HUAYI, 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; the datasheet gives gate-source voltage of ±20 V max, gate threshold of 1 V min to 3 V max at 250 µA, and gate-source leakage of ±100 nA max.
2 D passive Drain, the center position, which is shown as a trimmed stub and is connected to the exposed tab; the datasheet rates it 40 V drain-source and 80 A continuous at Tc=25℃.
3 S passive Source; the datasheet gives body-diode continuous source current as 80 A at Tc=25℃.
