CAD (KiCad official)

  • Symbol: BAT120C
  • Footprint: Package_TO_SOT_SMD:SOT-223
  • 3D model: SOT-223-4 (KiCad packages3D, STEP)
  • 3D model files: bat120c-etched.step / bat120c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat120c.step / bat120c.glb are the bare package body.
