CAD (KiCad official)

  • Symbol: BC817-40-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc817-40-tp-etched.step / bc817-40-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc817-40-tp.step / bc817-40-tp.glb are the bare package body.
