Abstract
The material for transient voltage suppressors is composed of at least two kinds of evenly-mixed powders including a powder material with non-linear resistance interfaces and a conductive powder. The conductive powder is distributed in the powder with non-linear resistance interfaces to relatively reduce the total number of non-linear resistance interfaces between two electrodes and, as a result, decrease the breakdown voltage of the components.
Claims8
A transient voltage protection material to reduce non-linear resistance interfaces between two electrodes and decrease breakdown voltage comprising:
- a) a non-linear resistor material having zinc oxide powder having a coating layer, the non-linear resistor material being comprised of zinc oxide powder in an amount between 50 and 97 percent by weight;
- and
- b) a conductive powder, the conductive powder being uniformly mixed with the non-linear resistor material.
