TVS – Varistors, MOVs, commonly known as Transient Voltage Suppression devices, are widely used in electronics, communication and electrical system applications. The ROV05-561K-S-2 is among the most popular surge protectors and is designed for applications such as circuit protection, over-voltage protection, and ESD protection. This article is focused on the application field and working principle of the ROV05-561K-S-2.

ROV05-561K-S-2 Application Field

The ROV05-561K-S-2 is designed to protect electronic components such as LEDs, ICs, MOSFETs, transistors, op-amps, power supplies, and relays from the harmful effects of external high-voltage surges, lightning, and ESD. Its capability to constrain transients, in the form of over-voltages, can prevent up to 600V transient pulses from being applied to sensitive circuits.

The ROV05-561K-S-2 is capable of withstanding up to 600V transient pulses without any physical damage to itself or to the equipment it is protecting. It is suitable for application in harsh industrial and consumer environments associated with high-voltage transients from the power, data, and signal lines. It is also suited for protection of diverse electronic components, varying from signal line components up to high-power applications, such as motors, transformers, and power supplies.

ROV05-561K-S-2 Working Principle

TVS devices, like the ROV05-561K-S-2, offer excellent transient protection as they act as a semiconductor zener diode. During an over-voltage surge event, the TVS is designed to limit the peak voltage and to clamp the voltage waveform to a safe level. In order to do this, TVS employs a unique voltage-dependent semiconductor junction that acts as a voltage clamp. When an over-voltage transient event occurs, such as a lightning strike, the TVS junction activates and clamps the voltage to the maximum pre-determined value.

The ROV05-561K-S-2 is a 600V, 10J Video Line Protector, which is designed to reduce the voltage surge to a low clamping voltage and dissipate it in order to avoid any damage to the equipment. Due to its inherent attenuation characteristics, this device limits both the current and the voltage, providing protection against unusual voltage transients lasting up to 10µs.

The ROV05-561K-S-2 device is capable of withstanding a wide variety of transient voltage conditions and is designed to protect communication lines, power lines, and other sensitive electronic equipment from voltages and currents much higher than the normal operating conditions.

Conclusion

The ROV05-561K-S-2 is a high-quality, low-cost surge protector designed for applications such as circuit protection, over-voltage protection, and ESD protection. Its 600V transient voltage protection and 10J Video Line Protector capabilities make the device suitable for use in harsh industrial and consumer environments and for protection of diverse electronic components. The ROV05-561K-S-2 is designed to clamp the voltage waveform to a safe level within 10µs to avoid any potential damage to sensitive electronic equipment.
