## CAD (KiCad official)

- Symbol: `TL051CDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tl051cdr-etched.step` / `tl051cdr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tl051cdr.step` / `tl051cdr.glb` are the bare package body.
