## CAD (KiCad official)

- Symbol: `PESD5V0L1BA-FS`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `pesd5v0l1ba-fs-etched.step` / `pesd5v0l1ba-fs-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesd5v0l1ba-fs.step` / `pesd5v0l1ba-fs.glb` are the bare package body.

## Provenance
