## CAD (KiCad official)

- Symbol: `BSS84LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bss84lt1g-etched.step` / `bss84lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bss84lt1g.step` / `bss84lt1g.glb` are the bare package body.
