CAD (KiCad official)

  • Symbol: DZQA6V8AXV5-7
  • Footprint: Package_TO_SOT_SMD:SOT-553
  • 3D model: SOT-553 (KiCad packages3D, STEP)
  • 3D model files: dzqa6v8axv5-7-etched.step / dzqa6v8axv5-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dzqa6v8axv5-7.step / dzqa6v8axv5-7.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
