ESD PROTECTION DEVICE AND MANUFACTURING METHOD THEREFOR

摘要

An ESD protection device includes a ceramic base material including a glass component; opposed electrodes including an opposed electrode on one side and an opposed electrode on the other side, which are arranged to have portions opposed to each other at a predetermined distance in the ceramic base material; and a discharge auxiliary electrode between the opposed electrodes, which is connected to each of the opposed electrode on the one side and the opposed electrode on the other side, and arranged to provide a bridge from the opposed electrode on the one side to the opposed electrode on the other side. A sealing layer to prevent ingress of the glass component from the ceramic base material into the discharge auxiliary electrode is provided between the discharge auxiliary electrode and the ceramic base material.
