FS3400

FOSAN · MOSFETs · SOT-23-3L

FS3400 from FOSAN, in a SOT-23-3L. 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; gate-source voltage is rated at ±12 V maximum, with a gate threshold voltage of 0.65 V min to 1.5 V max at ID=250uA.
2 S passive Source; continuous drain current is rated at 5.8 A at TA=25°C and the body diode forward drop is 1.2 V max at ISD=5.6A.
3 D passive Drain; drain-source voltage is rated at 30 V maximum, with pulsed drain current up to 23 A.

CAD (KiCad official)

  • Symbol: FS3400
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: fs3400-etched.step / fs3400-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fs3400.step / fs3400.glb are the bare package body.

Provenance

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

  • Datasheet: FOSAN datasheet (5 pp, sha256 d85d2cb86ec6095a, retrieved 2026-10-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-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).
