Varistors, also known as voltage-dependent resistors (VDRs), are a passive two-terminal electronic component. Consisting of semiconductor elements, it is an electrical component with both capacitance and resistance that vary with applied voltage. Varistors are widely used in power electronics and electrical systems for over-voltage protection and surge current absorption.

The V480LC80B is a high power voltage activated resettable over-voltage protection device from Vishay Semiconductor. This device is offered in an industry standard DO-205AA package. It is designed to provide circuit protection and over-voltage protection when an over-voltage event occurs and can be applied in DC and AC line protection, ESD protection and surge suppression applications.

The working principle of the V480LC80B device is to act as a voltage-dependent resistor. When the over-voltage occurs, the device’s internal resistance decreases dramatically to allow the current surge to be diverted away from sensitive circuitry and dissipated by the device. When the over-voltage is gone, the internal resistance increases so that the normal voltage will be able to flow through the device without interference from the voltage-resistor.

The applications of the V480LC80B device include over-voltage protection for DC/AC lines, ESD protection, surge protection and other applications such as power supplies, switches, computers, meters, white goods and consumer electronics. This device is ideal for use in systems where the possibility of damage by over-voltage is high or where the risk of component failure due to excessive voltage is high. In addition, the V480LC80B device has a low let-through voltage, making it ideal for use in high-voltage applications.

The V480LC80B device is designed to provide maximum protection from over-voltage and surge current events, while also maintaining a high degree of efficiency. In addition, the device has a wide operating temperature range, making it ideal for use in a range of applications and environments. The device is also designed to withstand high transient voltages, providing reliable and cost-effective protection even when dealing with high voltage fluctuations.

The V480LC80B device is a reliable, cost-effective solution for providing over-voltage protection and surge current protection. Its wide operating temperature range and high efficiency make it suitable for a wide range of applications. In addition, its high let-through voltage and low internal resistance make the V480LC80B device an ideal choice for high voltage applications.
