## CAD (KiCad official)

- Symbol: `BSD840N-VB`
- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`
- 3D model: SC-70-6 (KiCad packages3D, STEP)
- 3D model files: `bsd840n-vb-etched.step` / `bsd840n-vb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bsd840n-vb.step` / `bsd840n-vb.glb` are the bare package body.
