Varistors, MOVs and other surge protection devices are becoming increasingly popular in both consumer and industrial electronics. The most common form of surge protection device is a varistor, or voltage-dependent resistor. These devices are used to protect electronics against overvoltages, or "surges" caused by electrical storms and other transient events. The VE13M00251K is a varistor manufactured by TE Connectivity, and is designed for applications involving overvoltage protection.

The VE13M00251K is a thermally protected bidirectional varistor with a 300A open-circuit current. It has an operating temperature range of -40 to +125°C and a rated voltage of 325VAC. The device is intended for use in applications such as overvoltage protection, ESD protection, and circuit isolation. It is also suitable for use in consumer and industrial electronics, telecommunications, and automotive applications.

The working principle of a varistor is based on the fact that its resistance decreases as the applied voltage increases. This is known as "diode behaviour". When an overvoltage is applied, the varistor acts as a "short" and limits the voltage across the device. This, in turn, helps protect the connected circuits and components from possible damage due to excessive voltage. The VE13M00251K is designed to provide this level of protection by limiting its own voltage to 325VAC.

The VE13M00251K is also designed with a "thermal disconnect" feature which helps protect the device from overheating in the event of a prolonged overvoltage. This feature helps ensure the reliability of the protection provided by the device and helps to prevent circuit damage due to overheating. In addition, the device is UL and cUL recognized, indicating that it meets stringent safety requirements.

The VE13M00251K is designed for use in a variety of applications, including consumer and industrial electronics, telecommunications, and automotive applications. It is also suitable for use in ESD protection and circuit isolation applications. Its thermally protected feature ensures reliable protection against overvoltage, helping to ensure the safety of connected circuits. Its UL and cUL recognition also helps ensure the safety of those devices in which it is installed.
