Transient Voltage Suppressors (TVSs) are widely used in electronic circuits to protect them against voltage spikes caused by lightning strikes or excessive electrical noise, either from the power supply or from other circuits within the system. TVSs come in a variety of packages, from small semiconductor-based components, such as MOVs, to larger metal oxide varistors (MOVs), including the ROV10H751K-2.

The ROV10H751K-2 is a RoHS-compliant MOV with a disc-shaped housing 5.6 mm in diameter. It is designed to protect circuits against transient voltage up to 10kV, with an energy rating of 162J. The ROV10H751K-2 is intended for surface-mount applications, with its solderable terminals enabling easy installation onto printed circuit boards. It can also be mounted through hole for more robust applications.

The application fields for the ROV10H751K-2 include power supplies, consumer electronics, industrial applications, and automotive electronics. It is designed to protect circuits from surges in the power supply and also to protect against ESD (electrostatic discharge). It is also used in industrial applications such as pump drives, welding powers systems, and CNC controllers.

This particular type of Metal Oxide Varistor (MOV) is designed to clamp the voltage. It works by creating an open-circuit state whenever a voltage higher than its threshold is reached. When this happens, current is diverted away from the protected circuit.

The MOVs effect is created by its layered construction, which consists of a sintered ceramic disc of zinc oxide particles, sandwiched between two electrodes. Under normal conditions, the MOV behaves like an insulator, presenting a high impedance to current flow. When the MOV is subjected to a transient voltage higher than its threshold, the resistance of this ceramic layer drops dramatically, creating a low impedance path for current to flow.

The ROV10H751K-2 is designed to improve surge protection in a wide range of applications. The compact, easily installable MOV offers significant improvements in surge protection compared to traditional varistors and fuses. Its low profile and simple installation make it an ideal choice for those seeking to enhance surge protection in their electronics applications.
