CAD (KiCad official)

  • Symbol: SMAJ8.5A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj8-5a-etched.step / smaj8-5a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj8-5a.step / smaj8-5a.glb are the bare package body.
