HX3403

HX hengjiaxing · MOSFETs · SOT-23

HX3403 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; drive with VGS limited to ±12 V, threshold VGS(th) -0.5 V min to -1.5 V max, usable at gate voltages as low as 2.5 V.
2 S passive Source of the P-channel MOSFET; the body diode forward current is limited to -1.25 A.
3 D passive Drain; VDS maximum -30 V, continuous drain current -2.6 A and pulsed drain current -12 A.

CAD (KiCad official)

  • Symbol: HX3403
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: hx3403-etched.step / hx3403-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hx3403.step / hx3403.glb are the bare package body.
