## CAD (KiCad official)

- Symbol: `CMS03-TP`
- Footprint: `Diode_SMD:D_SOD-128`
- 3D model: SOD-128 (KiCad packages3D, STEP)
- 3D model files: `cms03-tp-etched.step` / `cms03-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cms03-tp.step` / `cms03-tp.glb` are the bare package body.
