SURFACE-MOUNTABLE ELECTRICAL CIRCUIT PROTECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a surface-mountable electrical circuit protection device for protection against electrostatic discharge (ESD).SOLUTION: An electrical circuit protection device includes: a first support substrate 130; and a first electrode 102A and a second electrode 102B formed on the first support substrate. The first electrode and the second electrode are formed from a conductive material. The electrical circuit protection device further includes: a first bonding pad 122 having a first cavity formed in the first and second electrodes; a second support substrate 120 disposed on the first bonding pad and having a second cavity formed therein; and a voltage variable material 106 disposed within the first cavity and the second cavity and electrically connected to the first electrode and the second electrode. The electrical circuit protection device further includes: a second bonding pad 112 disposed on the second support substrate; and a third support substrate 110 disposed on the second bonding pad.SELECTED DRAWING: Figure 3
