HSS3401A

HUASHUO · MOSFETs · SOT-23

HSS3401A from HUASHUO, in a SOT-23. 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; controls the P-channel MOSFET, with gate-source voltage limited to ±12 V and threshold of -0.5 to -1.3 V (typ. -0.9 V).
2 S passive Source of the P-channel MOSFET; rated for continuous drain current of -4.0 A at TA=25℃ (-3.2 A at 70℃).
3 D passive Drain of the P-channel MOSFET; drain-source voltage rated -30 V, continuous -4.0 A and pulsed -12 A.
