## CAD (KiCad official)

- Symbol: `DF2S5.6FS`
- Footprint: `Diode_SMD:D_SOD-923`
- 3D model: SOD-923 (KiCad packages3D, STEP)
- 3D model files: `df2s5-6fs-etched.step` / `df2s5-6fs-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `df2s5-6fs.step` / `df2s5-6fs.glb` are the bare package body.
