CAD (KiCad official)

  • Symbol: ESDULC12VD3B-TP
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esdulc12vd3b-tp-etched.step / esdulc12vd3b-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esdulc12vd3b-tp.step / esdulc12vd3b-tp.glb are the bare package body.
