TVS - or transient voltage suppressors - are devices which act as an auxiliary circuit between the main electrical circuit and the ground or the power supply. These devices are usually applied in order to protect the eletrical components from spikes, noise, and rapid voltage fluctuations. ROV07H271K-2 is a type of TVS, and it is specifically ideal for consumer and residential gadgets. Below is an overview of its operating principle and application field.

Working Principle

The ROV07H271K-2 device works when the voltage across its terminals climbs beyond its breakdown rating. When this occurs, the device becomes an electrical conductor and rapidly dissipates the energy through the ground or power supply. The device should be connected across the terminals responsible for delivering and receiving power in order to protect the circuits. Although the device works effectively in dissipating the voltage or current surge, it is also quite vulnerable and can be easily damaged by too much energy, so please take note.

Application Field

The ROV07H271K-2 is primarily an over-voltage protector used to guard the regular systems from voltage transients and spikes. It is often used in consumer electronics and appliances, such as heated water beds, hair curlers air conditioners, and computers. Due to its high clamping voltage, the device is also widely used in the automotive industry in applications where no leakage current requirement exists. In addition, this device has a fast response and a low clamping voltage, making it ideal for protecting system from lightning and surge-induced transients.

Conclusion

ROV07H271K-2 is a widely used TVS device which is suitable for protecting consumer electronics and appliances from voltage spikes and transients. It is highly reliable, and its low clamping voltage and fast responding speed make it effective against lightning and surges. While it offers a great deal of protection, it is highly vulnerable to damaging energy and should be handled with caution.
