TVSs (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are well known components for controlling overvoltage and surge protection in electronic systems. ROV07-220L is a MOV device designed to provide reliable protection in a wide range of extreme environmental conditions such as high temperature, humidity and vibrations.

ROV07-220L is a high-density, low-capacitance overvoltage protection component that fits easily into a limited space for system protection. It offers 10kA surge of suppression with low clamping voltage of 11V Max. It also features low total capacitance, high-speed turn-on time and excellent over-temperature protection. The ROV07-220L is designed to meet the IEC 61000-4-5 overvoltage immunity requirements and is compliant with the latest RoHS Directive.

The ROV07-220L is a surface-mount device (SMD) package with 7 pins. The pins can be configured in either straight or offset arrangement due to its diagonal pinout. The component is capable of operating over a wide temperature range of -40°C to +125°C. It is also equipped with a corona shield terminal and external ground connections for improved protection. The device can be used in a variety of applications including audio/video equipment, test instrumentation, telecommunications equipment, and medical device systems.

ROV07-220L is based on MOV technology which works by slowly diverting high voltage or current away from sensitive components or circuits. It is designed to allow a low voltage or current to pass through its terminals while protecting against abrupt changes in voltage or current. The device employs an alternate path of conduction for diverting excessive voltages or currents. The MOV acts like a short circuit when exposed to high voltages, allowing the current to flow through it instead of the load circuit it is protecting. This is known as the \'clamping\' action which helps to minimize voltage stress on the device.

To ensure effective operation, MOVs must be properly designed and sized for their purpose. The design includes determining the maximum working voltage, the peak pulse current and the maximum energy stored in the device. The size of the MOV depends on the desired response time and on the type of surge expected. The design also must take into account the device’s inductance, capacitance and line resistance.

To protect electronics from damage due to overvoltage and surge events, the ROV07-220L is a cost effective and reliable solution. Its low capacitance, high level of protection and wide operating temperature range makes it suitable for a variety of applications. It provides optimum protection for low-capacitance circuits with faster turn-on time and excellent over-temperature protection. With its simple vertical and horizontal angle pinout, ROV07-220L is able to fit easily into tight corner and confined spaces in the printed circuit board.
