Surge protection is an important design requirement in many applications, ranging from household electrical equipment to industrial equipment. The V68RA16 is a device specifically designed to protect against transient overvoltages including lightning and power cross surge. It is a Varistor-MOV (Voltage Dependent Resistor-Metal Oxide Varistor) designed for use in DC circuits.

A varistor is a two-terminal nonlinear component that exhibits a highly nonlinear resistance-voltage characteristic. It is also known as a voltage-dependent resistor (VDR). A MOV is a device which consists of a tantalum oxide layer sandwiched between two electrodes. It offers high voltage protection by clamping the voltage to a maximum level. Both Varistors and MOVs are used for voltage suppression and transient protection.

The V68RA16 is a device that combines the functionality of a Varistor and a MOV into one package. The device has a voltage (temperature) dependent resistance in series with a nonlinear resistance section. This combination results in an overcurrent protection circuit that offers excellent protection against fast transients in power applications.

The operation of the V68RA16 is quite straightforward. When the incoming voltage exceeds the clamp voltage (maximum surge current threshold) the varistor will reduce the current by increasing its resistance. This is due to the avalanche voltage of the device. At the same time, the nonlinear resistance section will begin to reduce the current without generating a voltage spike. As a result, the device provides protection against voltage surges while keeping the power supply voltage under control.

The V68RA16 is designed to be used in a wide variety of power applications, including automotive, appliances, power tools, and industrial equipment. It offers excellent protection against transients due to its low breakdown voltage, fast response time, and low maximum clamping voltage. In addition, the device is also highly durable and can withstand up to 800 volts for an extended period of time.

The V68RA16 is a valuable component for any power system that requires surge protection. its unique combination of Varistor and MOV technology provides excellent transient protection, while its compact size makes it ideal for use in a variety of applications. Whether in automotive, power tools, appliances, or industrial equipment, the V68RA16 is a reliable and cost effective solution for surge protection.
