HX3400B

HX hengjiaxing · MOSFETs · SOT-23

HX3400B 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 of the MOSFET, with a gate-source voltage rating of ±12 V (VGS) per the absolute maximum ratings.
2 S passive Source terminal of the MOSFET; the datasheet gives no specific limit for this pin beyond the pin assignment and schematic.
3 D passive Drain terminal of the MOSFET, rated for a drain-source voltage of 30 V (VDS) and a continuous drain current of 5.8 A at Tj=125℃.
