TVS-Varistors, MOVs, are widely used in various electronic fields. V12ZU05PX2855 is a typical product among these kinds of devices, which mainly works as a protector in a higher level of lightning condition. The basic working principle of V12ZU05PX2855 is to provide surge protection from lightning-induced transient voltage when connecting to the mains supply.

Generally, the working performance of V12ZU05PX2855 can be divided into two key functions: Current Limiting and Clamping. During a transient surge event, V12ZU05PX2855 can clamp the voltage at a specified level or current limit the current to maintain the voltage lower than a specific values so that the downstream devices and circuit may not be over voltage. In order to achieve this, V12ZU05PX2855 contains a Zener diode, a resistor and a varistor. When a surge occurs, the configured Zener diode can clamp the voltage at a specified level and the resistor can limit the current so that the downstream device can be protected. Also, the material and construction of the varistor allows it to “absorb” and reduce the amplitude of the surge.

The V12ZU05PX2855 is applicable to the applications ref. to IEC 61643/EN 61643 DSL, communication systems, data networks, industrial equipment and many other electronic equipment as well. Additionally, its features, such as, high surge capacity, low max. operating voltage, small size, low profile, low cost, high operational temperature etc., make it perfectly adopted to the specific uses. In other words, the expected operation performance could be accomplished with the normal circumstance.

In conclusion, V12ZU05PX2855 provides a high performance of protection performance, which is suitable for many different applications. The combination of high surge capacity, low max. operating voltage and small size, makes it ideal for various enclosures and other narrow place applications. Furthermore, its low profile and low cost also makes it attractive to customers.
