CAD (KiCad official)

  • Symbol: SL44HE3_B
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMC) (KiCad packages3D, STEP)
  • 3D model files: sl44he3-b-etched.step / sl44he3-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl44he3-b.step / sl44he3-b.glb are the bare package body.
