CAD (KiCad official)

  • Symbol: P6SMB47CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA (KiCad packages3D, STEP)
  • 3D model files: p6smb47ca-etched.step / p6smb47ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p6smb47ca.step / p6smb47ca.glb are the bare package body.
