CAD (KiCad official)

  • Symbol: P6SMB7.5A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: p6smb7-5a-etched.step / p6smb7-5a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p6smb7-5a.step / p6smb7-5a.glb are the bare package body.
