YONGYUTAI · MOSFETs · SOT-23

SI2301 from YONGYUTAI, 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. Controls the channel; VGS(th) typ -0.62 V, absolute max VGS = ±10 V. Drive to a negative VGS (relative to source) to enhance the P-channel.
2 S passive Source. Typically tied to the higher potential (e.g. VBUS) in a high-side P-channel switch topology.
3 D passive Drain. Channel current path to the load; ID = -2.2 A continuous, -8 A pulsed. BVDSS = -20 V. Body diode (drain-to-source) VSD max -1.5 V at IS = -0.75 A.

  • Symbol: SI2301
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: si2301-etched.step / si2301-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2301.step / si2301.glb are the bare package body.

Provenance

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

  • Datasheet: YONGYUTAI datasheet (3 pp, sha256 5da0b6fea01173ce, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
