HYG120P06LR1D

HUAYI · MOSFETs · TO-252

HYG120P06LR1D from HUAYI, in a TO-252. 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 gate-source voltage is rated at ±20 V, with a threshold of -1.0 V to -3.0 V at IDS=-250uA.
2	D	passive	Drain, which is also the exposed tab on the TO-252-2L; rated for -60 V drain-source and -55 A continuous at Tc=25°C.
3	S	passive	Source; carries the continuous source/drain current of -55 A at Tc=25°C, and the body diode forward voltage is -1.2 V max at -20 A.
