TVS - Varistors, MOVs

The MOV-14D182K is a Transient Voltage Suppressor (TVS) device with two separate technologies: a Varistor (MOV) and a Metal Oxide Varistor (MOV).

A Varistor is a voltage dependent resistance device that can act as a protective circuit when an overvoltage, also known as overstressing, occurs. It works by reducing the voltage applied to an electrical device. The MOV-14D182K has a maximum clamping voltage of 1500 volts and a peak pulse current of 17.6 amperes.

The Metal Oxide Varistor (MOV) works by clamping transients and surges with a peak pulse current of 10 amperes. This type of TVS device is able to support spikes with lower power dissipation. The MOV-14D182K has a peak pulse rating of up to 15A.

The MOV-14D182K is designed to provide robust protection against high-voltage transients and surges, such as lightning strike and electrostatic discharge. Its high clamping voltage can reduce overvoltage and can protect against voltages up to 1500V, making it the ideal choice for applications in automotive and industrial environments.

The MOV-14D182K is a bi-directional static voltage suppressor that is able to provide protection for both positive and negative transients within the normal operating voltage range. This device also features a high overshoot capability and low leakage current, allowing for high insulation performance.

In automotive applications, the MOV-14D182K can be used for protection of power and signal lines, such as in electronic shift actuators, air bag ignition circuits and ECU power supply lines. In industrial applications, the MOV-14D182K can be used in power supply systems, LED light drivers, power measurement and power switching equipment.

The MOV-14D182K is built with a low thermal resistance package, which helps ensure that it can withstand the heat generated by sudden surges and spikes. The device also has a wide operating temperature range of -55°C to +125°C, making it suitable for extreme temperature applications.
