ESD5B5CM

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

ESD5B5CM 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 of the two terminals of the bidirectional ESD/TVS clamp, which the datasheet rates for a 5.0 V reverse working voltage (VRWM) and protects one I/O line. The text does not identify this pin's function individually.
2 2 passive The other terminal of the bidirectional ESD/TVS clamp, which the datasheet rates for a 5.0 V reverse working voltage (VRWM) and protects one I/O line. The text does not identify this pin's function individually.

CAD (KiCad official)

  • Symbol: ESD5B5CM
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5b5cm-etched.step / esd5b5cm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5b5cm.step / esd5b5cm.glb are the bare package body.
