CAD (KiCad official)

  • Symbol: E-L6219DS013TR
  • Footprint: Package_SO:SO-24_5.3x15mm_P1.27mm
  • 3D model: SO-24-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: e-l6219ds013tr-etched.step / e-l6219ds013tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); e-l6219ds013tr.step / e-l6219ds013tr.glb are the bare package body.
