CAD (KiCad official)

  • Symbol: SMBJ210CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj210ca-etched.step / smbj210ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj210ca.step / smbj210ca.glb are the bare package body.
