VC020103V121WP

The VC020103V121WP is a semi-conditioned Varistor, Metal Oxide Varistor (MOV), an electrical component which is used to protect electronic or computer systems from drastic voltage spikes. It is a commonly used transient voltage surge suppressor (TVS).

Application Field

The VC020103V121WP is used for protection against voltage surges in telecommunications and consumer areas. It can be used in a wide range of applications, including internetworking, broadband, audio/video, industrial equipment, datacom/telecom, and consumer electronics. Furthermore, this integrated circuit can be applied in digital and analog circuits, power supplies, motor controls, radio-antennas and other equipment subject to common-mode transient surge voltages.

Working Principle

The VC020103V121WP has a functional voltage rating of 18V and a clamping voltage rating of 30V. Its Varistor feature follows a unidirectional characteristic. This means that the surge current will be dissipated following the absorbing characteristic curve. The power dissipation levels are designed to protect against both Line and Neutral. The MOV does this by clamping the voltage when it reaches a certain critical point maximizing the surge current, thus turning the device into a short circuit and limiting the amount of voltage that passes through the system.

The VC020103V121WP is an integrated circuit with an over-voltage protection circuit. It has a high speed switching time and a trigger current up to 3mA. This ensures the maximum protection against voltage spikes. Its metal oxide layer provides a positive threshold, offering superior stability, low and predictable clamping voltages.

The VC020103V121WP is also designed for ESD and lightning protection. Its Lightning Protection feature is designed to operate at high frequencies such as H-field, disrupting and dissipating unintentional voltage spikes. This integrated circuit can operate in temperatures ranging from -40°C to +125°C.
