HX3401B

HX hengjiaxing · MOSFETs · SOT-23-3L

HX3401B from HX hengjiaxing, in a SOT-23-3L. 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 of the P-channel MOSFET; absolute maximum gate-source voltage VGS is ±12 V.
2 S passive Source terminal of the P-channel MOSFET, shown as the source in the schematic and the reference for the gate-source voltage.
3 D passive Drain terminal of the P-channel MOSFET; drain-source voltage VDS is -30 V and continuous drain current ID is -4.2 A at TC=25°C.
