CAD (KiCad official)

  • Symbol: SA2B-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: sa2b-e3-etched.step / sa2b-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sa2b-e3.step / sa2b-e3.glb are the bare package body.
