It is low capacitance less than 0.3pF, therefore most suitable for ESD measures of the super-high-speed signal.

Good ESD withstand.(Contact/air Discharge 15kV)

What is the ESD suppressor?

ESD Suppressor is ESD protection device using gap discharge.

  • ESD suppressor protects Electric devices from ESD by utilizing the ability to decrease its resistance value rapidly when high voltage is applied to ESD Suppressor.
  • ESD Suppressor contributes to ensure the signal quality of High-speed serial data line and high frequency circuit in normal use (not applied high voltage).
  • Functions of ESD Suppressor

    ・Passing normal signal through to the protected element
    ・Protecting the element by flowing ESD current to GND

  • V-I characteristics of ESD Suppressor

    When ESD suppressor is applied to high voltage,
    current flows with voltage drop.
