Transient Voltage Suppression (TVS) devices have become a popular choice for surge protection in today’s electronic circuity. Varistors and Metal Oxide Varistors (MOVs) are two common forms of TVS that are used for this purpose. The ROV07H151K-2 is a type of Varistor, commonly referred to as a Varistor Disc.

Application Field

Varistors are most commonly applied in situations where overvoltage and power surges need to be suppressed, such as with AC/DC converters, energy supplies, and various other electrical devices. As a Varistor Disc, the ROV07H151K-2 is designed to provide multi-stage protection from a wide range of fluctuations in voltage. It is capable of providing up to 150V of peak protection, making it ideal for use on advanced power supplies, microcontroller-based boards, and small electronic circuits.

Working Principle

Varistors work by using a special semiconductor material to allow the device to respond to changes in voltage. This material is made up of RV101 and RV102-type layers, which are then connected to the ROV07H151K-2 leads. When there is a surge of voltage, the RV101 layer will conduct the surge away from the circuit, while still allowing low voltage signals to pass through the device. This provides a suppressor effect, allowing the device to protect the circuit from voltage variations.

The ROV07H151K-2 also uses a special capacitance-based design method to provide further protection from voltage spikes. This design creates a barrier between the line voltage and the device, helping to protect against fast transients. In addition, the device is also designed to provide protection from high frequency noise and EMC interference, making it ideal for applications where EMC protection is necessary.

The ROV07H151K-2 Varistor Disc also features a low leakage current. This allows the device to safely dissipate the energy from minor surges without experiencing excessive heat. This helps to ensure that the device will not be damaged if the surge is too intense, protecting both the device and the circuit from damage.

Conclusion

The ROV07H151K-2 is a type of Varistor, designed to protect circuits from voltage surges, transients, and interference. It is capable of providing up to 150V of peak protection, making it ideal for protecting advanced electronics from damage. The device also features a low leakage current and a capacitance-based design method, providing enhanced protection from EMC interference. The ROV07H151K-2 is a widely used Varistor Disc and offers excellent value for money when compared to other TVS devices.
