CAD (KiCad official)

  • Symbol: HNTJD5121NT1G
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: hntjd5121nt1g-etched.step / hntjd5121nt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hntjd5121nt1g.step / hntjd5121nt1g.glb are the bare package body.
