ESD5Z3V3

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

ESD5Z3V3 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 TVS diode, connected to the protected I/O line (VRWM 3.3V max, breakdown 5.0V min at 1mA for ESD5Z3V3).
2 A passive Anode of the unidirectional TVS diode, connected to ground (ESD per IEC 61000-4-2 ±30kV air, ±22kV contact).

CAD (KiCad official)

  • Symbol: ESD5Z3V3
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5z3v3-etched.step / esd5z3v3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5z3v3.step / esd5z3v3.glb are the bare package body.
