TVS (transient voltage suppressor) devices, also commonly referred to as Varistors or MOVs (Metal Oxide Varistors), are electrical components that protect sensitive electronics from momentary, transient power spikes that can cause damage or loss of data. They are designed to handle and dissipate large electrical spikes or surges that would otherwise damage or destroy the electronic device it is attached to. The V420LA7PX1347 is a type of varistor designed to protect sensitive electronics in, for example, television sets, cell phones, medical equipment and other consumer or industrial electronics.

The major function of the V420LA7PX1347 is to protect against overvoltage events such as lightning strike, power surge, or power reversal. It acts as a clamping device that will absorb over-voltage and limit it to a safe level. This type of varistor also works as a filter for removing undesired frequencies. If the voltage exceeds the rated value, the varistor will start to conduct, but be sure to check the current flow – it’s important to ensure that a safe limit is not exceeded.

The V420LA7PX1347 has a voltage range of 28 volts to 420 volts, making it an ideal choice for the majority of applications that require a voltage rating of up to 420 volts. It also comes with an insulation resistance of 100 mega ohms or greater at 500 Volts DC. The varistor also boasts a clamping voltage of 13 V. Additionally, its response time in discharging surge current is very quick, typically less than 0.1ns.

The most important aspect of the V420LA7PX1347 is its working principle. It is a non-linear resistor whose resistance value varies according to the voltage applied to it. It consists of multiple layers of metal oxides between two conductors and when the voltage applied to it exceeds the rated breakdown voltage, the varistor starts to conduct abruptly and the voltage is limited to a safe level, protecting the device. As the varistor is made up of metal oxide, it also has the capability to dissipate unwanted voltage spikes.

The V420LA7PX1347 is an ideal choice for protecting sensitive electronic equipment from transient over-voltage events. Its built-in non-linear resistance can limit voltage and its metal oxide construction gives it the ability to dissipate the surge current quickly and efficiently. Its wide voltage range, high leakage resistance, and fast response time make it an ideal choice for applications that require protection against transient over-voltage events.
