## CAD (KiCad official)

- Symbol: `MM5Z16AWT`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `mm5z16awt-etched.step` / `mm5z16awt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mm5z16awt.step` / `mm5z16awt.glb` are the bare package body.
