ESD5Z24

MDD（Microdiode Electronics） · ESD Protection Devices · SOD-523

ESD5Z24 from MDD（Microdiode Electronics）, 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 single-line ESD protection diode, rated for a 24 V reverse working voltage and ±15 kV air / ±8 kV contact ESD per IEC 61000-4-2 Level 4; the extracted text does not state whether this pin is the anode or cathode.
2 2 passive Other terminal of the single-line ESD protection diode, rated for a 24 V reverse working voltage and ±15 kV air / ±8 kV contact ESD per IEC 61000-4-2 Level 4; the extracted text does not state whether this pin is the anode or cathode.

CAD (KiCad official)

  • Symbol: ESD5Z24
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5z24-etched.step / esd5z24-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5z24.step / esd5z24.glb are the bare package body.
