CAD (KiCad official)

  • Symbol: SMB10J30A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smb10j30a-etched.step / smb10j30a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smb10j30a.step / smb10j30a.glb are the bare package body.
