CAD (KiCad official)

  • Symbol: 2.0SMBJ58CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: 2-0smbj58ca-etched.step / 2-0smbj58ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2-0smbj58ca.step / 2-0smbj58ca.glb are the bare package body.
