## CAD (KiCad official)

- Symbol: `OPA317IDCKT`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `opa317idckt-etched.step` / `opa317idckt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa317idckt.step` / `opa317idckt.glb` are the bare package body.
