HX3400S

HX hengjiaxing · MOSFETs · SOT-23

HX3400S from HX hengjiaxing, 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 terminal; gate-source voltage is rated at VGS ±12 V (absolute maximum), and gate threshold VGS(th) is 0.5 V min, 0.9 V typ, 1.5 V max at VDS=VGS, ID=250µA.
2 S passive Source terminal; continuous source current (diode conduction) is rated at IS 0.6 A.
3 D passive Drain terminal; drain-source voltage is rated at VDS 30 V and continuous drain current at ID 5.8 A (TA=25°C, TJ=150°C).
