CAD (KiCad official)

  • Symbol: MMSZ5232B-TP
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz5232b-tp-etched.step / mmsz5232b-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz5232b-tp.step / mmsz5232b-tp.glb are the bare package body.
