CAD (KiCad official)

  • Symbol: SMBJ5369B-MS
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj5369b-ms-etched.step / smbj5369b-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj5369b-ms.step / smbj5369b-ms.glb are the bare package body.
