ESD PROTECTION DEVICE

摘要

Disclosed is an ESD protection device wherein the ESD characteristics can be easily adjusted and stabilized. An ESD protection device (10) comprises: (a) a ceramic multilayer substrate (12); (b) at least a pair of discharge electrodes (16, 18), which are formed on the ceramic multilayer substrate (12) and face each other with a space therebetween; and (c) external electrodes (22, 24), which are formed on the surface of the ceramic multilayer substrate (12) and connected with the discharge electrodes (16, 18).  The ESD protection device (10) also comprises, in the region for connecting the discharge electrodes (16, 18), an auxiliary electrode (14) wherein a metal material (34) and a semiconductor material are dispersed.
