## CAD (KiCad official)

- Symbol: `S9012-TA`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92-2.54mm (KiCad packages3D, STEP)
- 3D model files: `s9012-ta-etched.step` / `s9012-ta-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `s9012-ta.step` / `s9012-ta.glb` are the bare package body.
