CAD (KiCad official)

  • Symbol: DDZ5V1BQ-7
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: ddz5v1bq-7-etched.step / ddz5v1bq-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz5v1bq-7.step / ddz5v1bq-7.glb are the bare package body.
