## CAD (KiCad official)

- Symbol: `GBU2510`
- Footprint: `Diode_THT:Diode_Bridge_Vishay_GBU`
- 3D model: GBU (KiCad packages3D, STEP)
- 3D model files: `gbu2510-etched.step` / `gbu2510-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gbu2510.step` / `gbu2510.glb` are the bare package body.
