CJ2312

Changjing · MOSFETs · SOT-23

CJ2312 from Changjing, 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 GATE input Gate terminal of the N-channel MOSFET, rated for a gate-source voltage of ±8.0 V (VGS) with a gate threshold of 0.45 V to 1.0 V.
2 SOURCE passive Source terminal, the reference for VGS, with a continuous source-drain diode current rating (IS) of 1.04 A.
3 DRAIN passive Drain terminal, rated for a drain-source voltage (VDS) of 20 V, a continuous drain current of 5 A (t=5s) and a pulsed drain current of 20 A.

CAD (KiCad official)

  • Symbol: CJ2312
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cj2312-etched.step / cj2312-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj2312.step / cj2312.glb are the bare package body.
