CAD (KiCad official)

  • Symbol: 1SMB5913BT3G
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: 1smb5913bt3g-etched.step / 1smb5913bt3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1smb5913bt3g.step / 1smb5913bt3g.glb are the bare package body.
