CAD (KiCad official)

  • Symbol: DDZ27BSF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: ddz27bsf-7-etched.step / ddz27bsf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddz27bsf-7.step / ddz27bsf-7.glb are the bare package body.
