Title:
ESD PROTECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/027553
Kind Code:
A1
Abstract:
Provided is an ESD protection device having excellent ESD properties.
The ESD protection device (1) is equipped with a ceramic insulating material (10), first and second discharge electrodes (21, 22) and a discharge-assisting section (51). The discharge-assisting section (51) is an electrode capable of decreasing a discharge inception voltage between the first discharge electrode (21) and the second discharge electrode (22). The discharge-assisting section (51) comprises a sintered body containing electrically conductive particles and also containing semiconductor particles and/or insulating particles. Among the ceramic insulating material (10) and the discharge-assisting section (51), at least the discharge-assisting section (51) contains an alkali metal component and/or a boron component. The content of the alkali metal component and/or the boron component in the discharge-assisting section (51) is larger than that in the ceramic insulating material (10).
