CAD (KiCad official)

  • Symbol: BEP0300SB
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: bep0300sb-etched.step / bep0300sb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bep0300sb.step / bep0300sb.glb are the bare package body.
