CAD (KiCad official)

  • Symbol: SMLJ22AHE3-TP
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: smlj22ahe3-tp-etched.step / smlj22ahe3-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smlj22ahe3-tp.step / smlj22ahe3-tp.glb are the bare package body.
