V420LT40CPX2855

TVS – Varistors, MOVs stand for Transient Voltage Suppressor (TVS) and Metal Oxide Varistor (MOV). Generally, MOVs and TVS are used in the protection of electronic circuits from voltage transients arising from lightning and other electrostatic discharges. The V420LT40CPX2855 is an example of such protective device, but it has some unique features as well.

Application Field

The V420LT40CPX2855 is mainly used in the protection of audio and video circuits against transient voltages up to 4K volt. This device prevents transients that could potentially damage the component circuitry, as well as providing overload protection. The design has been optimized to provide a high level of protection while minimizing the additional loading and power consumption.

This device is especially suitable for protecting all kinds of consumer electronics products, such as DVD / Blu-ray players, home audio products, laptops, flat panel TVs, computers, consoles, and gaming systems. The device can be used in both grid-connected and battery-powered systems. It is also widely used in automotive environments for protection against excessive voltage, load dump, and line transients.

Working Principle

The V420LT40CPX2855 is a 2-pin TVS device that offers 4kV of protection. It is designed with a polymeric structure for low clamping voltage and high surge capability. Its low power consumption and small size makes it ideal for various situations, such as protection of consumer electronics, automotive, medical and industrial applications.

When the V420LT40CPX2855 is exposed to a transient voltage spike, the device will absorb most of the energy and dissipate it as heat. This will protect the connected components of the circuit from any potential damage due to the transient. The device also provides fast response times to ensure that the transient is absorbed before it can damage the connected components.

The device is designed to remain permanently inserted in the circuit and, because of its low power consumption, it will not contribute to any noticeable increase in power consumption. The device is also designed to have a long service life, even after being exposed to numerous transient events.

The protection offered by the V420LT40CPX2855 is well suited for consumer electronics and automotive applications. It has been designed to suit various applications, including local, remote, short circuit, and ground fault protection as well as overload protection.
