BC856BDW

YFW · Bipolar (BJT) · SOT-363

BC856BDW from YFW, in a SOT-363. 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 E1 passive Emitter of transistor TR1 (PNP); -VEBO max rating 5 V.
2 B1 input Base of transistor TR1; -VEBO 5 V, collector current -IC up to 100 mA.
3 C2 passive Collector of transistor TR1 per the datasheet's pin list (3. Collector); -VCEO 65 V for BC856DW, -IC 100 mA max.
4 E2 passive Emitter of transistor TR2 (PNP); -VEBO max rating 5 V.
5 B2 input Base of transistor TR2; -VEBO 5 V, collector current -IC up to 100 mA.
6 C1 passive Collector of transistor TR2 per the datasheet's pin list (6. Collector); -VCEO 65 V for BC856DW, -IC 100 mA max.

CAD (KiCad official)

  • Symbol: BC856BDW
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: bc856bdw-etched.step / bc856bdw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc856bdw.step / bc856bdw.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: YFW datasheet (3 pp, sha256 5a09b6a70ac6193f, retrieved 2026-10-18, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
