## CAD (KiCad official)

- Symbol: `RB520S-30`
- Footprint: `Diode_SMD:D_SOD-523`
- 3D model: SOD-523 (KiCad packages3D, STEP)
- 3D model files: `rb520s-30-etched.step` / `rb520s-30-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rb520s-30.step` / `rb520s-30.glb` are the bare package body.
