SI2318DS

TECH PUBLIC · MOSFETs · SOT-23

SI2318DS from TECH PUBLIC, 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 limit is ±20 V, with threshold VGS(TH) of 1 V min to 3 V max at ID = 250 µA.
2 S passive Source of the N-channel MOSFET; carries continuous drain current up to 3.9 A (16 A pulsed) and is the anode of the body diode.
3 D passive Drain of the N-channel MOSFET; drain-source voltage rated 40 V, RDS(on) 45 mΩ max at VGS = 10 V and 62.5 mΩ max at VGS = 4.5 V.

  • Symbol: SI2318DS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: si2318ds-etched.step / si2318ds-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2318ds.step / si2318ds.glb are the bare package body.
