BCW68HR

Nexperia · Bipolar Transistors - BJT · SOT-23

BCW68HR from Nexperia, 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 terminal; base current IB is limited to -100 mA DC and -200 mA peak (single pulse, tp ≤ 1 ms).
2 E passive Emitter terminal; emitter-base voltage VEBO is limited to -5 V with the collector open.
3 C passive Collector terminal; collector-emitter voltage VCEO is limited to -45 V (open base) and collector current IC to -800 mA DC (-1 A peak).

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

  • Symbol: BCW68HR
  • 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, 1.0 mm tall, datasheet A, midpoint of min and max). 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: bcw68hr-etched.step / bcw68hr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcw68hr.step / bcw68hr.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (13 pp, sha256 34d738ff19de3deb, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-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).
