CAD (KiCad official)

  • Symbol: MURS140T3G
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: murs140t3g-etched.step / murs140t3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); murs140t3g.step / murs140t3g.glb are the bare package body.
