TVS - Varistors, MOVs are used in the electronics industry to protect circuits from transient overvoltage surges. The V14E420PL2B7 is part of a class of television suppression (TVS) devices specifically designed for clamping applications. These TVS devices serve the purpose of reducing transient overvoltages from reaching an electrical device’s circuits.
The V14E420PL2B7 is a14 kV surge protective device (SPD) with an IEC 61643-11 classification meaning it is indicated for indoor applications. This device provides over voltage protection with ultimate protection from sharp rising surges of very short duration. It has a low peak pulse current of 2kA and fast response time, allowing it to clamp and absorb any surge voltages while limiting the amount of energy available. It is composed of two components – a varistor and a Metal Oxide Varistor (MOV). In its simplest form, the device is composed of an electrolytic capacitor, a spark gap, a snubber network, and a varistor.
The varistor serves as a voltage-dependent resistance that changes its resistance depending on the voltage applied. The MOV is used to absorb any excess energy created by the varistor. This combination of components is what ultimately provides protection against electrical surges. As the voltage passing through the V14E420PL2B7 exceeds the breakdown voltage of the varistor, the varistor acts as a transistor and transfers the energy to the MOV. The MOV then absorbs the excess energy which prevents the voltage from reaching sensitive electronic components.
The V14E420PL2B7 can be used in a variety of applications where transient overvoltage protection is required. It is suitable for protecting circuits from power surges and spikes in power-lines, as well as providing lightning protection from power-line-induced surges. It is also suitable for protecting communications lines, as well as digital and audio signals, from transient overvoltage events. Additionally, it can be used in equipment such as telephone sets, modems, TVs, and home electronics.
The V14E420PL2B7 can also be used as a protective element in power supply circuits of various electronic and communication equipment. It provides protection against over voltage transients generated due to line voltage fluctuations, electrical noise, and switching transients. It works by clamping the transient voltage to a set voltage, absorbing the transient current, and limiting the clamping voltage. This protects the sensitive electronic components from being damaged or malfunctioning due to transient voltage.
In conclusion, the V14E420PL2B7 is a versatile surge protective device suitable for large range of applications. Its fast response time and ability to absorb energy make it a great choice for protecting sensitive electronic components from transient overvoltage events. Its simple two-component design also makes it easy to integrate into existing systems and circuits.
