CAD (KiCad official)

  • Symbol: SMBJ26AQ
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
  • 3D model files: smbj26aq-etched.step / smbj26aq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj26aq.step / smbj26aq.glb are the bare package body.
