A transient voltage suppressor (TVS) is an electronic component that is designed to protect sensitive electronics and power devices from damage due to electrical transients, such as those caused by switching components, static electricity, lightning, or electrostatic discharges. TVS devices come in two varieties, metal oxide varistors (MOVs) and silicon avalanche diodes (SADs). The ROV07H390K is a TVS device of the metal oxide varistor (MOV) variety.

MOVs are made of two plates, one zinc oxide and the other a steel or aluminum plate, sandwiched between two layers of electrodes. When a voltage spike is detected, current flows through the MOV, causing a change in electrical properties. This change in electrical properties is called a "avalanche breakdown," which absorbs the energy of the transient voltage spike.

MOV\'s are designed to handle larger transient voltage spikes than SADs because the MOVs have a higher surge current rating. This means that MOVs are well-suited for applications that require more protection from sudden surges and transients. The ROV07H390K is no exception, offering surge protection up to 390 volts.

The ROV07H390K is a varistor with a radial style lead and a wide operating temperature range from -55°C to 125°C. It has a high power rating of 510 mW, making it suitable for a variety of applications including automotive as well as industrial. It is also UL and VDE approved, making it suitable for use in safety-critical applications.

The ROV07H390K is often used in automotive and industrial applications, including motor controllers, generators, and power supplies. The device can be used to protect against overvoltages and surges in power lines, providing a secure connection between the power source and the component being protected. Additionally, the device can be used to filter high frequency signals, eliminating noise and interference while reducing power requirements, increasing the efficiency of the circuit.

In summary, the ROV07H390K is an extremely versatile and reliable device, providing reliable protection from transient voltage spikes in automotive and industrial applications. It can handle high voltage surges up to 390V, and its wide operating temperature range and high power rating makes it suitable for a variety of applications. It is also UL and VDE approved, making it suitable for use in safety-critical applications.
