CAD (KiCad official)

  • Symbol: SMLVT3V3
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
  • 3D model files: smlvt3v3-etched.step / smlvt3v3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smlvt3v3.step / smlvt3v3.glb are the bare package body.
