The Important Role Of MST® Easy-maintainable High Purity Electronic Grade Zinc Oxide In Varistor


One Important properties of MST® high purity electronic grade zinc oxide film-pressure sensitivity (mainly expressed in the characteristics of nonlinear voltammetry).

When the Easy-maintainable High Purity Electronic Grade Zinc Oxide varistor is subjected to an applied voltage, there is a threshold voltage, that is, the varistor voltage (V). When the applied voltage is higher than this value, it enters the breakdown voltage region. At this time, a small change in voltage will cause a rapid increase in current, and the amplitude of the change is characterized by the nonlinear coefficient (a). This feature makes zinc oxide varistor materials widely used in overcurrent protection of various circuits.

Due to the rapid development of integrated circuits, low voltage and low power are increasingly required for varistor. The varistor voltage used for overvoltage protection of integrated circuits is generally (1OV. With the development of very large scale integrated circuits, varistor with high a value and varistor voltage <5V becomes more and more important. Oxidation The varistor property of zinc varistor comes from its grain boundary effect, which is mainly related to the number of interfaces. The more the number of interfaces, the greater the varistor voltage; conversely, the smaller. Increase the particle size of zinc oxide crystal or reduce the thickness of zinc oxide material It is an effective way to reduce the number of currents flowing up the interface of zinc oxide crystals and reduce their varistor voltage. Therefore, high purity grade zinc oxide films have significant low-pressure varistor properties.

MST chemical Easy-maintainable High Purity Electronic Grade Zinc Oxide is made by indirect method with high purity and low impurities. It can meet all the requirement of varistor. That can keep customers' product quality stable.
