## CAD (KiCad official)

- Symbol: `MOC3052M`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `moc3052m-etched.step` / `moc3052m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `moc3052m.step` / `moc3052m.glb` are the bare package body.
