HCEZ24V

Public Made by Adom

by adom

HXY MOSFET Electrostatic And Surge Protection (TVS/ESD), SOD-523. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: HCEZ24V
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: hcez24v-etched.step / hcez24v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hcez24v.step / hcez24v.glb are the bare package body.
