CAD (KiCad official)

  • Symbol: SMBJ28CA-E3
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMBJ) (KiCad packages3D, STEP)
  • 3D model files: smbj28ca-e3-etched.step / smbj28ca-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj28ca-e3.step / smbj28ca-e3.glb are the bare package body.
