TVS (Transient Voltage Suppressor), MOVs (Metal Oxide Varistors) and ERZ-V14D180 (a particular device) are invaluable elements used in electrical and electronic circuits. These devices act as protection against overvoltage and are used for several applications. In the following section, the application fields and working principle of the ERZ-V14D180 will be explored in detail.

The ERZ-V14D180 is an axial leaded varistor specifically designed for applications in automotive and other high-voltage circuits. It is capable of withstanding up to 1500V, has a response time of less than 1ns and is compliant with AEC-Q200. This makes the device ideal for dealing with inrush current, ESD (electrostatic discharge), EMI (electromagnetic interference) and other overvoltage disturbances. Moreover, the ERZ-V14D180 is a low capacitance component with a capacitance of less than 0.01pF, which makes it well-suited for high-frequency circuits.

In terms of its application fields, the ERZ-V14D180 is most commonly used in automotive circuits such as engine control units, airbag systems, powertrain control modules and control units of various sensors. It is also commonly used in industrial circuits, telecommunications circuits, consumer electronics and medical equipment. In each of these application fields, the device helps to protect the circuits and ensure their safe operation.

In terms of its working principle, the ERZ-V14D180 is composed of a sintered metal oxide material between two copper terminations. This material has high breakdown voltage and nonlinear resistance characteristics. When a voltage exceeding the breakdown voltage is applied across the device, it reduces the voltage to a safe level. The increase in current across the device causes its temperature to rise which, in turn, increases the resistance of the material. This helps to further reduce the voltage to a safe level. The device is self-restoring, which means that it will reset itself to its original state and be ready for the next voltage surge.

In conclusion, the ERZ-V14D180 is a versatile device with a wide range of application fields and a simple yet effective working principle. It is an essential component used to protect circuits against overvoltage and other disturbances.
