CAD (KiCad official)

  • Symbol: DDC143EH-7
  • Footprint: Package_TO_SOT_SMD:SOT-563
  • 3D model: SOT-563 (KiCad packages3D, STEP)
  • 3D model files: ddc143eh-7-etched.step / ddc143eh-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddc143eh-7.step / ddc143eh-7.glb are the bare package body.
