CAD (KiCad official)

  • Symbol: BAT54H
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: bat54h-etched.step / bat54h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54h.step / bat54h.glb are the bare package body.
