S9012 2T1

Changjing · Bipolar (BJT) · SOT-23

S9012 2T1 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 BASE passive Base terminal of the PNP transistor; the datasheet gives no separate base limit, and the absolute maximum emitter-base voltage is -5 V (VEBO) with a collector current of -500 mA (IC).
2 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base breakdown voltage V(BR)EBO is -5 V minimum at IE=-0.1 mA, and the absolute maximum emitter-base voltage VEBO is -5 V.
3 COLLECTOR passive Collector terminal of the PNP transistor; absolute maximum collector-base voltage VCBO is -40 V, collector-emitter voltage VCEO is -25 V, collector current IC is -500 mA, and collector power dissipation PC is 300 mW.

CAD (KiCad official)

  • Symbol: S9012 2T1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: s9012-2t1-etched.step / s9012-2t1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s9012-2t1.step / s9012-2t1.glb are the bare package body.
