SI2312BDS

TECH PUBLIC · MOSFETs · SOT-23

SI2312BDS 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; controls the channel, with VGS rated ±8 V maximum and a threshold of 0.45 V min to 1 V max at ID=250µA.
2 S passive Source; main current terminal, with continuous drain current rated 5.5 A and body-diode forward current IS of 5.5 A max.
3 D passive Drain; rated 20 V maximum drain-source voltage (VDS), with continuous drain current 5.5 A and pulsed 18 A.

  • Symbol: SI2312BDS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: si2312bds-etched.step / si2312bds-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); si2312bds.step / si2312bds.glb are the bare package body.
