ROV10-391K

TVS - Varistors, MOVs

ROV10-391K is a unidirectional Thyristor Surge Protective Device, also known as TVS (Transient Voltage Suppression). It is mainly used for protecting various electronic components against voltage spikes, lightning and other high-energy transients. ROV10-391K is a compact two-line design with highly effective EMI/RFI suppression functions. The device features an internal voltage clamping mechanism which, when triggered, limits the peak voltage to a set value.

Working Principle

ROV10-391K is designed and constructed using a system of integrated MOSFETs, thyristors, and integrated circuit resistors. This device works on a negative-going transient voltage. When a negative-going transient voltage is present, the device senses the voltage and internally triggers and shunts the current away from the protected circuit.

The device is particularly effective in stopping high-voltage spikes. As high-voltage spikes are too quick to be effectively handled by a resistor or capacitor, the device comes in very handy when it comes to protecting sensitive circuits and components from overvoltage damage.

Once triggered, the active circuitry quickly conducts the surge current away from the sensitive area. At the same time, the EMI/RFI filter circuitry filters out any harmful or erroneous signal frequencies that may be present.

Application Field

ROV10-391K TVS devices are widely used in protecting computer networks, peripheral devices, data lines and other electronics from high-energy transients and other voltage surges.

In the telecommunications industry, TVS devices such as the ROV10-391K are used to protect electronic equipment from lightning and electrostatic discharges, and to reduce EMI/RFI interference.

In the automotive industry, ROV10-391K TVS devices are used in various components and systems, such as spark plugs, transmission systems, exhaust control systems, airbag systems, and fuel injection systems.

Conclusion

ROV10-391K TVS devices are reliable and effective in protecting sensitive circuits and components from high-energy transients and other voltage surges. The device features an internal voltage clamping mechanism which, when triggered, limits the peak voltage to a set value. This is an invaluable feature for protecting sensitive parts that can otherwise be damaged by excessive voltages.

Overall, ROV10-391K TVS devices offer an ideal solution for protecting electronics from high-energy transients and other voltage surges.
