BC546BBK

(DIOTEC) · Bipolar Transistors - BJT · TO-92

BC546BBK from (DIOTEC), in a TO-92. 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 C passive Collector; VCEO max 65 V (BC546), 45 V (BC547), 30 V (BC548/549); IC max 100 mA dc, 200 mA peak.
2 B passive Base; peak base current IBM max 200 mA, and emitter-base voltage VEBO max 5 V.
3 E passive Emitter; peak emitter current IEM max 200 mA, VEBO max 5 V with collector open.

CAD (KiCad official)

  • Symbol: BC546BBK
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: bc546bbk-etched.step / bc546bbk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc546bbk.step / bc546bbk.glb are the bare package body.

Provenance

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

  • Datasheet: (DIOTEC) datasheet (3 pp, sha256 889a83aa8ac5ef11, retrieved 2026-10-28, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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.
