## CAD (KiCad official)

- Symbol: `P6SMB22CA`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `p6smb22ca-etched.step` / `p6smb22ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `p6smb22ca.step` / `p6smb22ca.glb` are the bare package body.

## Provenance
