BCW66GVL

Nexperia · Bipolar Transistors - BJT · SOT-23

BCW66GVL 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 passive Base terminal; base current IB is limited to 100 mA and peak base current IBM to 200 mA (single pulse, tp ≤ 1 ms).
2 E passive Emitter terminal; emitter-base voltage VEBO is limited to 5 V.
3 C passive Collector terminal; collector current IC is limited to 800 mA (peak ICM 1 A) with VCEO 45 V and VCBO 50 V.

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

  • Symbol: BCW66GVL
  • 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: bcw66gvl-etched.step / bcw66gvl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcw66gvl.step / bcw66gvl.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (14 pp, sha256 6a1bc1da706875ce, 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).
