BC856A

YONGYUTAI · Bipolar (BJT) · SOT-23

BC856A from YONGYUTAI, 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's device limits for this part are emitter-base voltage VEBO -5 V and collector current IC -0.1 A.
2 EMITTER passive Emitter terminal of the PNP transistor; emitter-base breakdown V(BR)EBO is -5 V with IE=-1μA and IC=0.
3 COLLECTOR passive Collector terminal of the PNP transistor; for the BC856 the collector-emitter voltage VCEO is -65 V and the collector power dissipation PC is 200 mW.

CAD (KiCad official)

  • Symbol: BC856A
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc856a-etched.step / bc856a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc856a.step / bc856a.glb are the bare package body.
