CAD (KiCad official)

  • Symbol: SBRT3U45SA-13
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: sbrt3u45sa-13-etched.step / sbrt3u45sa-13-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sbrt3u45sa-13.step / sbrt3u45sa-13.glb are the bare package body.
