CAD (KiCad official)

  • Symbol: K180SA
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: k180sa-etched.step / k180sa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); k180sa.step / k180sa.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
