V320LS40BP

TVS - Varistors, MOVs

The V320LS40BP is a transient voltage suppressor (TVS) device designed to protect systems and equipment from current surges and voltage spikes. It can protect against a variety of electrical phenomena including voltage transients, electromagnetic interference, and other sources of high-frequency noise. It acts as a circuit breaker, dissipating energy and temporarily stopping current flow before it can damage electronic components.

The V320LS40BP comes in a hermetically sealed, UL-recognized package that provides stability and protection against the most persistent surge threats. Its over-voltage protection capability exceeds the maximum junction temperatures of most semiconductor devices. It is ideal for a wide range of applications, including telecom, automotive, and industrial equipment.

Working Principle

The V320LS40BP is a shunt connective varistor composed of a metal oxide film. Through the shunt connection, the device provides an electrical path for the sudden ducting of surges and voltage spikes. The device will absorb excess energy from these over-voltage conditions, limiting voltage transients to a safe level.

The device works by allowing a controlled amount of current to flow through it when over-voltage conditions occur. This current flows through the device and is dissipated as heat, preventing it from damaging downstream circuits. When the over-voltage condition subsides, the device closes a circuit and current flow stops.

The device also undergoes a threshold set point, at which point it begins to conduct in the presence of transient over-voltages. This set point can be adjusted by altering the design of the device. This allows the device to be customized to the application it is intended for.

Applications

The V320LS40BP is suitable for use on a number of different applications, including telecom, automotive, and industrial equipment, as well as any application in which electrical transients may occur.

In the telecom industry, the device is commonly used to protect communication cables, routers, and switches. Its hermetically sealed package ensures that its electrical properties are not degraded by humidity or other environmental conditions. Additionally, its high over-voltage protection capabilities make it suitable for protecting telecom systems from lightning or power surges.

In the automotive industry, the V320LS40BP can be used to protect against voltages generated by collisions or other faults. Its high over-voltage protection capabilities make it well suited for this application. Additionally, its hermetically sealed package ensures that its electrical properties are not degraded by the temperature fluctuations associated with automotive applications.

Finally, the device is suitable for industrial equipment, particularly for use against power surges or voltage spikes. Its hermetically sealed package makes it robust against harsh industrial environments, while its protection capabilities ensure that any over-voltage conditions are properly dealt with, preventing them from damaging downstream components.
