Varistors, MOVs, and other transient voltage suppressors, also known as TVS devices, are used to protect electrical and electronic components, as well as the systems and devices in which they are installed, from abnormal voltage fluctuations. The ROV07-391K is a TVS device especially designed to help protect electronic devices from voltage transients caused by electrostatic discharges, inductive switching, and electrical fast transients generated by lightning and power line transients. It is suitable for a wide range of power supply and low frequency distribution circuits.

The ROV07-391K is a bidirectional axial leaded disc varistor suitable for voltage protection applications between 12-30VDC. It is designed to provide overvoltage protection by clamping the rising voltage and offering the lowest possible clamping voltage, allowing it to protect sensitive and/or expensive components from voltage fluctuations and transients. It is a zener diode, a diac, and a transient voltage suppressor all in one. As with other forms of TVS devices, the ROV07-391K works by providing a low saturation voltage and fast response when facing abnormal voltage fluctuation. Its bidirectional transient voltage clamping allows it to suppress any voltage that exceeds its clamping voltage.

The ROV07-391K has a wide range of applications in a variety of electronic devices and systems thanks to its low capability, bidirectional clamping feature, nonlinear resistance, surge protection ability, and suitability for low frequency distribution circuits. Its voltage protection capability makes it perfect for application such as protecting power supplies, DC control systems, power busbar, and instrumentation from lightning, ESD, and other electrical surges.

The ROV07-391K is designed to withstand transient voltage spikes as high as 30VDC. The device is also capable of hardening the line by increasing the capacitance, allowing it to spare other devices from further damage. This means the ROV07-391K is capable of limiting the voltage to the desired level, shutting off the power if the voltage exceeds the upper or lower limits. All this makes the ROV07-391K ideal for protecting valuable equipment and sensitive components from transient overvoltages.

The ROV07-391K features a reverse leakage current of up to 10uA, while its maximum capacitance is 2 x 10-uF. It has a rated voltage of 24V and peak pulse current of up to 2A. Its capacitance is 4.5KV as tested under a 8/20us waveform, and its maximum reverse voltage is 25Vdc. The device also features an insulation resistance of over 100M ohms, and a temperature range of -40C to +85C.

In conclusion, the ROV07-391K is a reliable and effective transient voltage suppressor designed to help protect sensitive components from overvoltage transients. Its bidirectional transient protection and low saturation voltage ensure that it clips any harmful voltage well before it can do any damage. It has a wide range of applications, and is capable of shielding components from lightning, ESD, and power line transients. All its features, combined with its affordability, make the ROV07-391K the perfect solution for protecting valuable components from transient overvoltages.
