## CAD (KiCad official)

- Symbol: `2SC1008`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92 (KiCad packages3D, STEP)
- 3D model files: `2sc1008-etched.step` / `2sc1008-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sc1008.step` / `2sc1008.glb` are the bare package body.
