TVS (transient voltage suppression) diodes, also known as varistors, are commonly used surge protectors in power distribution systems, and are available in many shapes and varieties. MOVs (metal oxide varistors) are direct energy absorbers which provide protection against power surge related damage to components, circuits, and systems. ROV10-561K-2, which is a MOV (metal oxide varistor) type of TVS (transient voltage suppression) diode, is designed to protect circuits from damage caused by potential overvoltage through a process called clamping.

An ROV10-561K-2 is rated for a voltage of 561V with a breakdown voltage of 670V, and a maximum sustained operational current of 85A. The diode is also split into two modules, each rated to protect against a voltage spike of up to 295V. This makes the ROV10-561K-2 well-suited for use in applications where protection against a wide range of voltages is necessary. It is also an ideal choice for automotive and other industrial applications where voltage levels tend to fluctuate often.

When subjected to a surge in voltage, the diode begins to conduct current. This current is then redirected to ground, thereby preventing damage to the protected device and circuit. The surge voltage is “clamped” to a level below the operational voltage, thus protecting the circuit from overvoltage damage.

ROV10-561K-2 diodes also feature high surge and energy rated protectors. It can handle a surge of up to 50A (8/20μs, 1.2/50μs) with a maximum surge energy rating of 200J, thereby providing additional protection. The diode is also designed to dissipate heat quickly, making it particularly suitable for those applications that require protection against short and intense overvoltage.

ROV10-561K-2 is available in both active and passive modes. The active mode offers continuous protection, while the passive mode only activates when a surge occurs. This makes them ideal for applications that require continuous or intermittent protection, such as industrial equipment, automotive systems, and consumer electronics.

In conclusion, ROV10-561K-2 transient voltage suppression diodes are an excellent choice for surge protection in industrial and automotive applications. Their wide voltage range and high surge energy rating make them suitable for use in a wide variety of both active and passive applications. Their ability to quickly dissipate heat also makes them a great choice for those applications that require protection against short and intense surges.
