Transient voltage suppressors (TVSs) or varistors are one of the basic categories of protective components. They are often referred to as MOVs (metal oxide varistors). They protect circuits from over-voltage transients, under-voltage events, lightning and other electrical disturbances. The VC120614A300DP is a typical example of a transient voltage suppressor.

Application Fields

The VC120614A300DP provides protection for a wide range of electronic equipment, including power supplies, switches, telecommunications, motor controllers, and server systems. Its applications include telecom, lightning, power surge protection in remote control systems, low voltage protection, low voltage DC-DC converters, and micro-controller based systems.

Working Principle

The VC120614A300DP is constructed with a non-linear resistance material, commonly known as a varistor. The varistor has a very high resistance gain in response to a high voltage and acts as a current limiter. The device also contains a protective circuit designed to divert over-voltage or current transient waves away from the sensitive components in a circuit and to protect them from damage.

The operating voltage of the VC120614A300DP is the maximum voltage before breakdown. The maximum surge current is a measure of the peak surge current the device can continuously withstand. The peak surge current capability is an important parameter for the protection of downstream components, particularly those associated with computers.

The VC120614A300DP offers a unique combination of long-term endurance and very low leakage current. It also provides low clamping voltage and a fast response time in case of emerging transient energy in the system. Its low breakdown voltage provides exceptional over-voltage protection in low voltage applications. This makes it an ideal choice for communications, data storage, power supplies and other applications.

Conclusion

The VC120614A300DP is a typical TVS/MOV component that provides excellent protection from transients, over-voltage, under-voltage, and lightning. Its low breakdown voltage and fast response time make it an ideal choice for low-voltage applications, such as communications and data storage. Its high surge current capability makes it suitable for use in power supplies, switches, motor controllers, and server systems.
