## CAD (KiCad official)

- Symbol: `SMA6J33CA`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
- 3D model files: `sma6j33ca-etched.step` / `sma6j33ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sma6j33ca.step` / `sma6j33ca.glb` are the bare package body.
