SE2305

SINO IC · MOSFETs · SOT-23

SE2305 from SINO IC, 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; gate-source voltage limited to ±12 V, threshold VGS(th) -0.4 to -1 V at ID=-250μA.
2 S passive Source of the P-channel MOSFET; drain-source voltage VDS is rated -20 V.
3 D passive Drain; continuous drain current -4.7 A, pulsed -20 A, VDS -20 V.

  • Symbol: SE2305
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: se2305-etched.step / se2305-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); se2305.step / se2305.glb are the bare package body.
