## CAD (KiCad official)

- Symbol: `SS5U100PA`
- Footprint: `Package_TO_SOT_SMD:TO-277A`
- 3D model: TO-277 (KiCad packages3D, STEP)
- 3D model files: `ss5u100pa-etched.step` / `ss5u100pa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ss5u100pa.step` / `ss5u100pa.glb` are the bare package body.
