TVS-Varistors, MOVs is an electrical device specifically designed to provide surge protection. They are type of semiconductor device that provides protection against transient over-voltages events, such as lightning or other power surges. This protection is provided by clamping the voltage passing through them to an acceptable level. A TVS-Varistor, MOV (Metal Oxide Varistor) is one type of varistor device which is designed to protect against over-voltages. ERZ-V05D180 is a high power, non-polar and Uni-directional TVS-Varistor, MOV with low capacitance.

Application Field

The ERZ-V05D180 is suitable for a wide range of applications. It is mainly used for protecting LAN/ISDN lines, telecom lines, computer, automotive electronics and AC power lines from over-voltages. One of the most common applications is in over-voltage surge protection, which is used when connecting sensitive equipment to vulnerable AC power lines. It is also extensively used for high voltage, AC/DC ballasted lighting installations. The device is also commonly used in situations where there is an overall need for transient voltage surge suppression.

Working Principle

The working principle of a TVS-Varistor, MOV is to clamp any over-voltages passing through it to an acceptable level. This is achieved by utilizing its non-linear voltage/current characteristics. It has a very low capacitance, typically of between 0.5 – 5 pF. This means that it will not significantly affect high speed digital signals passing through it. When an over-voltage is encountered, the device will provide isolation and protect the equipment involved from the harmful surges. This is achieved thanks to the device\'s ability to absorb the over-voltage energy and consequently reduce it to a safe level.

The ERZ-V05D180 features a symmetrical clamping voltage of 180V, which is suitable for most applications. It has a maximum peak pulse power of 5KW, providing protection against all but the most extreme levels of over-voltage. The device also has a wide temperature range, with an operating temperature of -40 °C to 125°C. This allows it to be used in a wide range of environments.

Conclusion

In conclusion, ERZ-V05D180 is a high power, non-polar, Uni-directional TVS-Varistor, MOV device and is suitable for a variety of applications. It has a symmetrical clamping voltage of 180V and a peak pulse power of 5KW, providing excellent protection against surges and over-voltages. In addition, the device\'s wide operating temperature range means that it can be used in a wide range of environments.
