CAD (KiCad official)

  • Symbol: BC847B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc847b-etched.step / bc847b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc847b.step / bc847b.glb are the bare package body.
