CAD (KiCad official)

  • Symbol: SZ1SMA10CAT3G
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: sz1sma10cat3g-etched.step / sz1sma10cat3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sz1sma10cat3g.step / sz1sma10cat3g.glb are the bare package body.
