## CAD (KiCad official)

- Symbol: `PESDMC2FD18VB`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `pesdmc2fd18vb-etched.step` / `pesdmc2fd18vb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesdmc2fd18vb.step` / `pesdmc2fd18vb.glb` are the bare package body.
