## CAD (KiCad official)

- Symbol: `KPESD3V3S1BL`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `kpesd3v3s1bl-etched.step` / `kpesd3v3s1bl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `kpesd3v3s1bl.step` / `kpesd3v3s1bl.glb` are the bare package body.
