SI2309S

BORN · MOSFETs · SOT-23-3L

SI2309S from BORN, 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 of the P-channel MOSFET, with a maximum gate-source voltage of ±20 V and a gate threshold voltage of -1.0 V min to -3 V max at ID = -250 uA.
2 S passive Source of the P-channel MOSFET, where the body diode forward voltage is -1.2 V max at IS = -1.2 A.
3 D passive Drain of the P-channel MOSFET, rated for -60 V drain-source voltage and -1.9 A continuous drain current at TA = 25 °C.

CAD (KiCad official)

  • Symbol: SI2309S
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: si2309s-etched.step / si2309s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2309s.step / si2309s.glb are the bare package body.

Provenance

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

  • Datasheet: BORN datasheet (5 pp, sha256 9b60bd86acc8cc03, retrieved 2026-10-28, tier: lcsc)
  • 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.
