## CAD (KiCad official)

- Symbol: `RB751VM-40`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `rb751vm-40-etched.step` / `rb751vm-40-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rb751vm-40.step` / `rb751vm-40.glb` are the bare package body.
