## CAD (KiCad official)

- Symbol: `BC847W`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `bc847w-etched.step` / `bc847w-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bc847w.step` / `bc847w.glb` are the bare package body.
