BCX71J

Nexperia · Bipolar (BJT) · SOT-23

BCX71J from Nexperia, in a SOT-23. 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 B passive Base terminal of the PNP transistor, shown as B on the graphic symbol; the datasheet gives no per-pin voltage or current limit for it.
2 E passive Emitter terminal of the PNP transistor, shown as E on the graphic symbol; the datasheet gives no per-pin voltage or current limit for it.
3 C passive Collector terminal of the PNP transistor, shown as C on the graphic symbol; the collector current limit is -100 mA (IC) and collector-emitter voltage is -45 V (VCEO) per the limiting values.

CAD (KiCad official)

  • Symbol: BCX71J
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bcx71j-etched.step / bcx71j-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcx71j.step / bcx71j.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (8 pp, sha256 863138e43bc78e08, retrieved 2026-10-09, 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.
