CAD (KiCad official)

  • Symbol: 1.5SMBJ58A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
  • 3D model files: 1-5smbj58a-etched.step / 1-5smbj58a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1-5smbj58a.step / 1-5smbj58a.glb are the bare package body.
