## CAD (KiCad official)

- Symbol: `S5MS-E3`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: DO-214AB(SMC) (KiCad packages3D, STEP)
- 3D model files: `s5ms-e3-etched.step` / `s5ms-e3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s5ms-e3.step` / `s5ms-e3.glb` are the bare package body.
