## CAD (KiCad official)

- Symbol: `3SMBJ5933B-TP`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `3smbj5933b-tp-etched.step` / `3smbj5933b-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3smbj5933b-tp.step` / `3smbj5933b-tp.glb` are the bare package body.
