AO3402

GOODWORK · MOSFETs · SOT-23

AO3402 from GOODWORK, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 GATE input Gate of the N-channel enhancement MOSFET; the datasheet limits gate-source voltage to VGS ±12 V.
2 SOURCE passive Source of the N-channel MOSFET; the datasheet gives a body diode forward voltage VSD of 1 V max at IS = 1 A, VGS = 0 V.
3 DRAIN passive Drain of the N-channel MOSFET; the datasheet limits drain-source voltage to 30 V and continuous drain current to 4 A at Ta = 25 ℃.

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: AO3402
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ao3402-etched.step / ao3402-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ao3402.step / ao3402.glb are the bare package body.

Provenance

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

  • Datasheet: GOODWORK datasheet (5 pp, sha256 a2a8bd54d32f4c4f, retrieved 2026-11-12, 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: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
