CAD (KiCad official)

  • Symbol: CEM3139
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cem3139-etched.step / cem3139-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cem3139.step / cem3139.glb are the bare package body.
