TVS (transient voltage suppressor) are a class of electrical protection components that protect electronic circuits from the damaging effects of transients. Varistors and metallic oxide varistors (MOVs) are two types of devices that make up the TVS family. The V180ZS20P is a type of varistor that is used for a variety of applications and can be found in electrical and consumer products. This article will discuss the application field of the V180ZS20P and its working principle.

The V180ZS20P is a 20V, 350A 10,000pF non-polar varistor. It offers protection against transients up to 1,100V and is widely used across consumer and industrial applications. Typical applications of the device include life safety systems, lightning detection systems, automotive systems, industrial equipment, and medical monitoring equipment. It is also used in solar power systems, photovoltaic systems, and other power systems that require protection from high voltage spikes.

The V180ZS20P is also known as a metal oxide varistor (MOV). MOVs are semiconductor voltage-dependent devices that provide a low-impedance path to ground when the voltage across them reaches a certain level. They are also known as voltage-dependent resistors (VDRs). MOVs are able to absorb and discharge large amounts of energy when activated. This is why they are commonly used to protect sensitive electronic circuits from damage caused by transients and overvoltages.

The V180ZS20P is composed of a variety of layers. The innermost core is an intrinsic semiconductor material, such as zinc oxide. This material forms the main electrical contact of the device. An oxide layer is then formed, which acts as an insulating layer around the semiconductor. The outermost layers are thin electrodes. These act as both the electrodes to activate the device and the contact points to the external circuit. Together, these layers provide a low-impedance path to ground when the voltage across them reaches a given level.

When the voltage across the V180ZS20P reaches its clamping voltage, also known as the “on voltage”, it acts as a low impedance path and dissipates the voltage in an orderly manner by channeling the current to ground. This prevents the current from damaging the protected equipment, allowing it to operate normally. Once the voltage across the device falls below the “off voltage”, the device resumes its high-impedance state and the circuit returns to normal operation.

In conclusion, the V180ZS20P is a metal oxide varistor (MOV) that is used in a variety of applications. It offers protection against transients up to 1,100V and has a clamping voltage and an off voltage. Its layers provide a low-impedance path to ground when the voltage across them reaches the given levels, protecting sensitive electronic circuits from damage caused by transients and overvoltages.
