## CAD (KiCad official)

- Symbol: `MOT1045D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `mot1045d-etched.step` / `mot1045d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mot1045d.step` / `mot1045d.glb` are the bare package body.
