Varistors, also referred to as voltage-dependent resistors (VDRs), are semiconductor devices that have a non-linear behavior of current with respect to voltage. The ROV14H201K-S is a sintered metal-oxide varistor (MOV) type TVS (Transient Voltage Suppressor) device specifically designed for the protection of high-speed power line and line-to-ground communication systems such as RS-232, USB, and other Ethernet applications. The MOV14 series is designed to provide up to 4 kilovolts of protection.

Application Field

The ROV14H201K-S can be used in a range of applications such as automotive, industrial and consumer electronics, IT equipment, telecommunications equipment, home appliances and more. The main application for this type of MOVs is for overvoltage protection, which means they are ideal for protecting electrical circuits and components that can be damaged or become faulty due to voltage spikes.

Working Principle

The working principle of the ROV14H201K-S is that when the applied voltage exceeds the varistor voltage, the varistor behavior changes from a low-impedance state to that of a high-impedance (or off-state) state. This change from a low-impedance state to a high-impedance state is known as clamping. The clamping characteristic is based on the ZnO element which has non-linear resistance behavior in response to voltage changes. When a voltage spike is applied, the resistance of the ZnO element increases dramatically and the resulting current will be relatively low. This current reduction helps to protect the circuit or equipment that is connected downstream.

Varistor Characteristics

The ROV14H201K-S varistor has several characteristics which make it particularly suitable for use in protection applications. The peak surge current capability is 15A (8/20μs), which means it can handle high current bursts without degrading or overheating. The V clamping voltage is 13V, which is an important parameter as it determines the maximum voltage that the varistor can handle without suffering from breakdown. The device also has a low capacitance of just 0.63pF (at 1MHz) which gives it excellent high-frequency characteristics. The combination of these features makes the ROV14H201K-S an ideal solution for protecting circuits and components from voltage transients.

Conclusion

In conclusion, the ROV14H201K-S is an ideal solution for overvoltage protection applications due to its robust design, low capacitance and high surge capability. It is designed to protect circuits and components from harmful voltage spikes, making it a reliable and cost-effective TVS MOVs device.
