AO3401

Guangdong Hottech · MOSFETs · SOT-23

AO3401 from Guangdong Hottech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate. High-impedance MOSFET control terminal. VGS(th) between -0.7 V and -1.3 V; absolute maximum VGS = ±12 V. Drives channel conduction between Drain and Source.
2 S passive Source. P-channel MOSFET source terminal, typically tied to the positive supply in high-side switching. Body diode anode is internally connected here (VSD ≈ -1 V at IS = -1 A).
3 D passive Drain. P-channel MOSFET drain terminal, typically tied to the load. VDS rated to -30 V; continuous ID = -4.2 A. Body diode cathode is internally connected here.

CAD (KiCad official)

  • Symbol: AO3401
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ao3401-etched.step / ao3401-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ao3401.step / ao3401.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Guangdong Hottech datasheet (4 pp, sha256 cd52f037371b3f5a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
