CAD (KiCad official)

  • Symbol: UDZSTE-1718B
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: udzste-1718b-etched.step / udzste-1718b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); udzste-1718b.step / udzste-1718b.glb are the bare package body.
