SI2300A

UMW · MOSFETs · SOT-23

SI2300A from UMW, in a SOT-23. 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: MOSFET gate terminal; gate-source voltage is rated at ±12 V (VGS) in the absolute maximum ratings.
2 S passive SOURCE: MOSFET source terminal; continuous source-drain (body diode) current is rated at 0.6 A (IS).
3 D passive DRAIN: MOSFET drain terminal; drain-source voltage is rated at 20 V (VDS) and continuous drain current at 6 A (ID).

CAD (KiCad official)

  • Symbol: SI2300A
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: si2300a-etched.step / si2300a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2300a.step / si2300a.glb are the bare package body.
