CAD (KiCad official)

  • Symbol: BAV23CA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: TO-236 (KiCad packages3D, STEP)
  • 3D model files: bav23ca-etched.step / bav23ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bav23ca.step / bav23ca.glb are the bare package body.
