## CAD (KiCad official)

- Symbol: `TYN616`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `tyn616-etched.step` / `tyn616-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tyn616.step` / `tyn616.glb` are the bare package body.
