ESD5Z3.3C

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

ESD5Z3.3C 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 1 passive One terminal of the TVS diode, connected to the protected I/O line, with a 3.3V reverse working voltage (VRWM).
2 2 passive Other terminal of the TVS diode, connected to ground or the return side, with a 3.3V reverse working voltage (VRWM).

CAD (KiCad official)

  • Symbol: ESD5Z3.3C
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5z3-3c-etched.step / esd5z3-3c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5z3-3c.step / esd5z3-3c.glb are the bare package body.
