## CAD (KiCad official)

- Symbol: `BZX584C3V0`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `bzx584c3v0-etched.step` / `bzx584c3v0-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx584c3v0.step` / `bzx584c3v0.glb` are the bare package body.
