## CAD (KiCad official)

- Symbol: `MURS460B`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `murs460b-etched.step` / `murs460b-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `murs460b.step` / `murs460b.glb` are the bare package body.

## Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
