SI2302S

FOSAN · MOSFETs · SOT-23

SI2302S from FOSAN, 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; threshold voltage VGS(th) 0.5-1.5 V (ID=250 µA, VGS=VDS); gate-source voltage rating ±10 V; gate leakage IGSS ≤ 100 nA at VGS=+10 V.
2 S passive Source; body-diode forward voltage VSD ≤ 1.5 V at IS=0.75 A, VGS=0 V; continuous drain current ID=2.5 A (referenced to source).
3 D passive Drain; BVDSS=20 V min (ID=250 µA); RDS(ON) 55/65 mΩ typ/max at ID=3.6 A, VGS=4.5 V; continuous current ID=2.5 A, pulsed IDM=12 A.

CAD (KiCad official)

  • Symbol: SI2302S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: si2302s-etched.step / si2302s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2302s.step / si2302s.glb are the bare package body.

Provenance

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

  • Datasheet: FOSAN datasheet (3 pp, sha256 43f860e133b46573, retrieved 2026-09-21, 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 0.2, primary claude-sonnet-4-6 (text+vision), consensus claude-opus-4-7 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
