BC846AQ-7-F

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

BC846AQ-7-F from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 B input Base; the top-view pin-out drawing shows B at the bottom-left lead, and the device is an NPN transistor with VEBO of 6.0 V (BC846/BC847) or 5.0 V (BC848).
2 E passive Emitter; the top-view pin-out drawing shows E at the bottom-right lead, with peak emitter current IEM of 200 mA.
3 C passive Collector; the top-view pin-out drawing shows C as the single lead on the top side, with continuous collector current IC of 100 mA and peak ICM of 200 mA.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: BC846AQ-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: bc846aq-7-f-etched.step / bc846aq-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc846aq-7-f.step / bc846aq-7-f.glb are the bare package body.

Provenance

  • Datasheet: Diodes Incorporated datasheet (7 pp, sha256 4c2c7141238f9de1, retrieved 2026-11-12, tier: manufacturer)
  • 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.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
