## CAD (KiCad official)

- Symbol: `CDBC5200-HF`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `cdbc5200-hf-etched.step` / `cdbc5200-hf-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cdbc5200-hf.step` / `cdbc5200-hf.glb` are the bare package body.
