Introduction

V07P420L2T is one type of transverse-flow pressure-sensitive varistor (TVS - Varistors, MOVs), which is suitable for over-voltage/over-current protection in power systems. It is usually made up of layers of metal oxides and ceramics, and works by providing a low voltage- drop path to ground when excessive voltage is applied. This helps protect electric circuits from damage caused by over-voltages and over-currents.

Application Field

V07P420L2T can be used as an over-voltage/over-current protection device in various power applications. It is suitable for protection of AC/DC power supplies, uninterruptible power supplies (UPS), power supplies used in industrial and commercial environments, and many other power systems. It is also widely used in LED lighting, home appliances, and medical equipment.

V07P420L2T can also be used for protection of printed circuit boards (PCB) and electronic control units (ECU) from over-voltage and over-current. It is suitable for use in various automotive applications, including reversing cameras, navigation systems, and safety systems. In addition, it is also applicable for railway equipment protection.

Working Principle

V07P420L2T is a transverse-flow varistor. It consists of stacked metal oxide and ceramic layers, which are called “elements”. The elements form a typical pressure-sensitive varistor, which means it has a relatively low voltage-drop across it when an excessive voltage is applied. This helps protect electric circuits by providing a low voltage-drop path to ground when an over-voltage or over-current is present.

When a voltage is applied across the varistor, the layers of metal oxide and ceramic create an internal electric field between them. When the internal field strength exceeds the breakdown strength of the material, current is allowed to flow across the device, forming a voltage-drop path to ground. This helps protect the electric circuits from being damaged by over-voltages or over-currents.

V07P420L2T also has a high thermal stability, which helps ensure that the device can withstand high temperatures during its operation. This helps to improve the reliability of the device, and ensures that it is able to protect electric circuits even in harsh conditions.

Conclusion

V07P420L2T is a type of pressure-sensitive varistor suitable for over-voltage/over-current protection in power systems. It is suitable for protection of AC/DC power supplies, LED lighting, home appliances, and many other applications. It has a low voltage-drop across it when an excessive voltage is applied, forming a path to ground, and a high thermal stability, which helps ensure its reliability. V07P420L2T can help ensure the safety of electric circuits from damage caused by over-voltages and over-currents.
