## CAD (KiCad official)

- Symbol: `DON70N03`
- Footprint: `Package_DFN_QFN:DFN-S-8-1EP_6x5mm_P1.27mm`
- 3D model: DFN5x6-8 (KiCad packages3D, STEP)
- 3D model files: `don70n03-etched.step` / `don70n03-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `don70n03.step` / `don70n03.glb` are the bare package body.
