## CAD (KiCad official)

- Symbol: `SSL310`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `ssl310-etched.step` / `ssl310-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ssl310.step` / `ssl310.glb` are the bare package body.
