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.
