CAD (KiCad official)

  • Symbol: 1SMA4735A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: 1sma4735a-etched.step / 1sma4735a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma4735a.step / 1sma4735a.glb are the bare package body.
