## CAD (KiCad official)

- Symbol: `AP2055K`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `ap2055k-etched.step` / `ap2055k-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap2055k.step` / `ap2055k.glb` are the bare package body.
