A ROV05H221K is an essential component of a wide range of industrial applications that require the discharge or transient regulation of voltage levels. It is a fairly common form of surge protection device and is typically used in high voltage DC applications, such as power supplies.

Application Field

The main application of a ROV05H221K is to protect equipment and systems from transient voltage surges. It is most commonly used in industrial applications but can also be found in consumer electronics devices. For example, it can be found in power supplies, UPS systems, motor control systems, PLCs, and audio electronics.

ROV05H221K components can also be used in medical applications such as pacemakers, implantable cardiac defibrillators, and other medical devices. They are also used in automotive applications, such as ECU circuitry and audio systems.

The device itself is relatively small and can be easily integrated into a variety of electronic systems. It is designed to be a cost effective solution for surge protection, providing reliable and consistent protection for a variety of electronic components.

Working Principle

The ROV05H221K works through a combination of thermal and electrical components. Its primary function is to protect against transient voltage spikes by limiting the amount of energy that can pass through it. When a voltage spike occurs, the ROV05H221K will act to divert some of the energy away from the component which it is protecting, thereby preventing damage.

The device consists of two terminals which are connected to a resistor and a zener diode. The resistor is used to limit the flow of current while the zener diode is used to protect against high voltages. In normal operation, the ROV05H221K will not have any effect on the flow of current, but in the event of a surge, it will act to limit the current flow.

When the voltage rises above a certain threshold, the zener diode will become activated and will act to divert the excess voltage away from the component which it is protecting. The resistor will then act to reduce the amount of current which passes through the diode, thus limiting the energy which can pass through it.

The ROV05H221K is an invaluable addition to any industrial system. It is a cost effective solution for surge protection, providing reliable and consistent protection for a variety of electronic components.
