Embodiment Construction

[0037]The invention is described in more detail with reference to the accompanying drawings, which depict preferred embodiments for carrying out the invention. However, the present invention has been illustrated in several embodiments, but should not be limited to the described embodiments.

[0038] In ESD protection circuits, most of the components are used to discharge ESD current in their first breakdown region. Components will not be damaged in their primary breakdown zone. This crash zone has its limits. This limit is the characteristic of the so-called secondary breakdown. When the component enters the secondary breakdown zone due to the overstress voltage or current, the component will cause permanent damage. Therefore, the current at the secondary breakdown point represents the upper limit of the ESD withstand capability of the ESD protection element. Transmission line pulse (transmission line pulse, TLP) system is a special measurement device specially designed to ...

Abstract

The invention relates to materials for an over-voltage protective element and an over-voltage protective element made of the materials. The materials comprise a non-conductor powder, a metal conductor powder and adhesive. The over-voltage protective element comprises a first electrode, a second electrode and a porous structure which is connected between the first electrode and the second electrode. The invention also relates to a method for manufacturing the over-voltage protective element and a method for adjusting the breakdown voltage of the over-voltage protective element.

Description

technical field [0001] The present invention relates to a material and structure of an overvoltage protection element. The invention also relates to a method of manufacturing said overvoltage protection element. Background technique [0002] Generally, overvoltage protection components are connected in parallel with the system to be protected under normal conditions, and are connected to the ground wire in a high-impedance state. When an abnormal charge enters the element (overvoltage is generated), the high impedance is instantly transformed into a low impedance, and the abnormal intrusion energy is introduced into the ground wire. [0003] Instantaneously changes from high impedance to low impedance, also known as element actuation. The voltage observed at that time is called the breakdown voltage, also called the trigger voltage. [0004] The principle of tip discharge is that the charge jumps from one conductor to another conductor, and the trigger voltage usually dec...
