## CAD (KiCad official)

- Symbol: `BD882-Y`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `bd882-y-etched.step` / `bd882-y-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bd882-y.step` / `bd882-y.glb` are the bare package body.
