TVS - Varistors, MOVs are both form of surge protectors. They both use the principle of voltage clamping to reduce voltages and protect against voltage surges. While the two share many similarities, they have distinct differences in application fields and working principles. This article will discuss the application field and working principle of the VC060309A200RP.

The VC060309A200RP is mainly used in industrial control systems, communication systems, equipment, and circuits, and other applications. It can be used as a noise-rejection element in dc-controlled relays, contact-closing circuit relays, transformers, coils, and other similar electrical noise generators. Furthermore, it can also be used as an isolation barrier for high input impedance electronic circuits, as well as an insulation protector for photovoltaic modules. Additionally, it is also extensively used in the automotive industry for vehicles equipped with electric start-stop technology (ESS).

The VC060309A200RP is a metal oxide varistor (MOV), which is composed of metal oxide semi-conducting material and encased in a plated cylindrical metal case. This device operates on the principle of voltage-clamping. It works by using the non-linear characteristics of the metal-oxide semi-conducting material to limit the voltage. When an overvoltage is applied, the device absorbs the energy from the surge and limits the voltage to a safe level. The varistor allows current to pass through it at normal voltages and restricts the current at higher voltages.

The VC060309A200RP has a categorized voltage sensitive characteristic referred to as a "knee voltage". This knee voltage is a fixed limit voltage point on the curves that exist in the semi-conducting materials above which the device begins to clamp. This is further classified into the following four regions: region one, where the voltage is clamped up to clamped voltage; region two, where the voltage is forced up to a limited peak value; region three, where the current is limited; and region four, where the voltage is tripped when it reaches the current trip level. The maximum continuous operating voltage (MCOV) is the peak level at which the device can operate continuously without failure.

In conclusion, the VC060309A200RP is an MOV used in a wide variety of applications, mainly in industrial control systems, communication systems, equipment, and circuits. It operates on the voltage-clamping principle by using the metal-oxide semi-conducting material to limit the voltage. The device has a categorized voltage sensitive characteristic known as a "knee voltage" and four associated regions. The maximum continuous operating voltage (MCOV) is the peak level at which the device can operate continuously without failure.
