BC856B

hongjiacheng · Bipolar (BJT) · SOT-23

BC856B 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 BC856B PNP transistor; the datasheet gives an emitter-base voltage limit of VEBO -5.0 V (IC=0, IE=-10 µA).
2 E passive Emitter terminal of the BC856B PNP transistor; the emitter-base breakdown voltage V(BR)EBO is -5.0 V minimum (IE=-10 µA, IC=0).
3 C passive Collector terminal of the BC856B PNP transistor; the BC856 collector-base voltage is -80 V and collector-emitter voltage is -65 V, with collector current limited to -0.1 A.

CAD (KiCad official)

  • Symbol: BC856B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc856b-etched.step / bc856b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc856b.step / bc856b.glb are the bare package body.
