CAD (KiCad official)

  • Symbol: SMBJ58CAX
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smbj58cax-etched.step / smbj58cax-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj58cax.step / smbj58cax.glb are the bare package body.
