TVS (transient voltage suppressor) or varistor is known for its performance in protecting circuits from transients or spikes. It when placed across a power line, it limits the maximum voltage that can pass and works by short circuiting the current flow across the line and to ground in a fashion that’s similar to a spark gap-based solution. Typical solutions employ either positive temperature coefficient (PTC) devices, gas tube and silicon avalanche diodes (SADs), or metal oxide varistor (MOV) devices.

MOV or Metal Oxide Varistors are design to limit large transient voltage peaks as such they are referred to as transient voltage suppressors (TVS). These devices are effectively a two-terminal variable resistor with a variable resistance that is inversely proportional to the applied voltage. There are many variants of the MOV, such as the ROV10H560K-2, which offer a range of options for suppressing transients.

The ROV10H560K-2 is a cost-effective protection device for all types of AC power systems and is available in low leakage current and with ultra-fast response time. The ultra-fast switching times make them ideal for protecting against high peak voltage and overvoltage transients in rapid cycles. The device has a two-stage operating response, with the first stage, being slow and the second stage being ultra-fast. The ROV10H560K-2 also operates very reliably, even under environmental conditions such as high temperature, high humidity and radiation.

The principle of operation of the ROV10H560K-2 is that it is designed to redirect energy from transients/spikes across the two terminals. This is done by the MOSFET, which is connected to the two terminals of the varistor. When a voltage spike occurs, the transistor is switched on and the current received is internal to the varistor. This diverted current is then dissipated as heat through the MOSFET, thus helping to protect the protected circuit or device from the transient.

The ROV10H560K-2 is well suited for a variety of applications, such as AC power systems, unpowered devices, surge-protection for motors and lightings, voltage-stabilizers, etc. It can also be used as an alternate to spark gaps in some applications. It can also be used in data and communication lines for providing protection from EMI/RFI, high voltage transients, and power surges. It can also be used in various consumer electronics like laptops, gaming consoles, power supplies, etc.

In summary, the ROV10H560K-2 is a versatile and cost-effective protection device designed to provide overvoltage and transient protection, especially in AC power systems. It is based on metal oxide varistor technology and with its two-stage operating response and ultra-fast switching speed, it can protect from transient voltage spikes quickly and effectively. It is suitable for a variety of applications including consumer electronics, AC power systems, motors and lighting, and communication systems, and is an ideal alternative to existing spark gap protection.
