BC857C

hongjiacheng · Bipolar (BJT) · SOT-23

BC857C from hongjiacheng, 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 B passive Base terminal of the BC857C PNP transistor, with emitter-base voltage limited to -5.0 V (VEBO) and collector current limited to -0.1 A.
2 E passive Emitter terminal of the BC857C PNP transistor, with emitter-base voltage limited to -5.0 V (VEBO) at IE = -10 µA.
3 C passive Collector terminal of the BC857C PNP transistor, rated for a collector-emitter voltage of -45 V (VCEO), a collector-base voltage of -50 V (VCBO), and a collector current of -0.1 A.

CAD (KiCad official)

  • Symbol: BC857C
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc857c-etched.step / bc857c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc857c.step / bc857c.glb are the bare package body.
