A TVS (Transient Voltage Suppressor) includes a Varistor, MOV (Metal Oxide Varistor) and ROV07H151K-S. TVS are robust components used to detect and protect against voltage or electrical transients. They are extremely important components in circuit protection, offering superior protection and performance. The ROV07H151K-S is a type of Varistor, which is used in various applications, depending on their characteristics.

Application Field of ROV07H151K-S

The ROV07H151K-S Varistor is designed to protect electronic circuits from transient overvoltages. It has a high breakdown voltage and can be used in various areas like automotive, communications, consumer and industrial electronics. It is especially suitable for protection devices such as switching devices, line protectors, AC/DC converters and surge protectors. ROV07H151K-S Varistors are also used as current limiting devices, so as to provide protection against short circuit and overcurrent.

Working Principle of ROV07H151K-S

The ROV07H151K-S Varistor works on the principle of non-linear current-voltage characteristic. When the current through the Varistor increases then the voltage across it also increases nonlinearly. The device has two basic characteristics. The first is that the current in the circuit remains limited to the specified value and the second is that when the voltage exceeds a certain level, the current through the Varistor gets reduced.

When a surge of voltage higher than the rated voltage is applied to the device, it will reduce the voltage to the normal operating level. This allows the device to protect the equipment or circuits from overvoltage or overcurrent. The Varistor also has a rapid response time, allowing it to react quickly and effectively to transient events.

The Varistor also has an energy limitation feature, meaning that it limits the energy dissipated in a circuit in order to protect the components. This feature prevents component damage from short circuit conditions or excessive power consumption.

Conclusion

The ROV07H151K-S Varistor is a type of TVS (Transient Voltage Suppressor) device, offering superior protection and performance in various applications. It works on the principle of non-linear current-voltage characteristic, allowing it to reduce the voltage to the normal operating level. It also has an energy limitation feature which prevents component damage from short circuit conditions or excessive power consumption.
