## CAD (KiCad official)

- Symbol: `SZA8.2A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC (KiCad packages3D, STEP)
- 3D model files: `sza8-2a-etched.step` / `sza8-2a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sza8-2a.step` / `sza8-2a.glb` are the bare package body.
