## CAD (KiCad official)

- Symbol: `LUDZS13BT1G`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `ludzs13bt1g-etched.step` / `ludzs13bt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ludzs13bt1g.step` / `ludzs13bt1g.glb` are the bare package body.
