Electrostatic discharge protection component

摘要

An electrostatic discharge protection component of an array type includes ceramic insulating substrate 12 ; varistor region 10 which is pasted on ceramic insulating substrate 12 and then is sintered integrally with ceramic insulating substrate 12 ; and at least one ground outer electrode 15 A and a plurality of input/output outer electrodes 15 B. Varistor region 10 includes at least one ground inner electrode 14 A, varistor layer 10 C and the plurality of input/output outer electrodes 15 B so as to form the plurality of varistors. Ground inner electrode 14 A is connected with ground outer electrode 15 A. This structure enables the protection component to be extremely thin.
