AO3401PSA

DOWO · MOSFETs · SOT-23

AO3401PSA from DOWO, 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 Gate input Gate of the P-channel enhancement-mode MOSFET; gate-source voltage is rated ±12 V.
2 Source passive Source of the P-channel MOSFET; the device is rated for a drain-source voltage of -30 V (VDS 30 V) and continuous drain current of 4.1 A.
3 Drain passive Drain of the P-channel MOSFET; rated -VDS 30 V, continuous drain current -ID 4.1 A, pulsed -IDM 20 A, and maximum power dissipation 1.2 W.

CAD (KiCad official)

  • Symbol: AO3401PSA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ao3401psa-etched.step / ao3401psa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ao3401psa.step / ao3401psa.glb are the bare package body.

Provenance

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

  • Datasheet: DOWO datasheet (7 pp, sha256 5173ff6ceaa48dcf, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
