CAD (KiCad official)

  • Symbol: STPS3170AF
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: stps3170af-etched.step / stps3170af-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps3170af.step / stps3170af.glb are the bare package body.
