## CAD (KiCad official)

- Symbol: `STTH6003CW`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247-3 (KiCad packages3D, STEP)
- 3D model files: `stth6003cw-etched.step` / `stth6003cw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stth6003cw.step` / `stth6003cw.glb` are the bare package body.
