ESD5Z5V0

MDD Microdiode Semiconductor · ESD And Surge Protection (TVS/ESD) · SOD-523

ESD5Z5V0 from MDD Microdiode Semiconductor, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the unidirectional ESD protection diode, connected to the protected I/O line (VRWM 5.0V, VB min 6.2V at 1mA for ESD5Z5V0), on the banded side of the package per the circuit diagram.
2 A passive Anode of the unidirectional ESD protection diode, normally connected to ground, per the circuit diagram (ESD per IEC 61000-4-2 ±30kV air, ±22kV contact).

  • Symbol: ESD5Z5V0
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5z5v0-etched.step / esd5z5v0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5z5v0.step / esd5z5v0.glb are the bare package body.
