TVS (Transient Voltage Suppressors), Varistors, and MOVs (Metal Oxide Varistors) are three types of active electronic components which are commonly used in circuit protection applications. The MLV1812E31403T is a transient voltage suppressor (TVS) designed specifically for automotive applications. This article will discuss the application fields and working principle of the MLV1812E31403T.

The MLV1812E31403T is a unidirectional transient voltage suppressor. It is designed with sensitive 1500W peak pulse dealing capabilities, and it can also withstand about 5A of continuous current. Additionally, the clamping voltage is 12.6V. These features make the MLV1812E31403T an ideal choice for automotive protection applications, such as 12V automotive systems. Other potential applications include power cables, cables for DC and AC motors, battery charging systems, and automotive audio systems.

Another application field for the MLV1812E31403T is power supply and power line protection. Power supply and power line protection is needed to prevent the power line from suffering from any overvoltage or overload damages. The MLV1812E31403T protects the power line by clamping the stray voltage that is present within the circuit. It also serves to protect the circuit from any surges or spikes that may occur through the supply. The clamping voltage is 12.6V, which makes the MLV1812E31403T an ideal choice for power supply and power line protection purposes.

The MLV1812E31403T is also suitable for lightning protection. This type of circuit protection is important to limit the voltage and current in the system, preventing it from significant damage due to lightning strikes. The MLV1812E31403T is designed with a 1500W peak pulse power rating that helps minimize dissipated energy and provides excellent reverse voltage protection. The MLV1812E31403T also has a low clamping voltage that prevents damage to the system even under high instantaneous voltages.

The MLV1812E31403T works by using two high-speed, low-resistance MOSFET transistors. These transistors create a feedback circuit and act as a voltage divider. They are activated by the presence of an overvoltage, which causes the transistors to shut off and direct the voltage to the suppressor. The suppressor then absorbs the excess voltage and dissipates it to prevent any damage to the system.

In conclusion, the MLV1812E31403T is a unidirectional transient voltage suppressor designed for automotive applications. It is suitable for power supply and power line protection, lightning protection, and other applications where high peak pulse power rating is needed. The MLV1812E31403T works by using two high-speed, low-resistance MOSFET transistors to create a feedback circuit and act as a voltage divider. The circuit absorbs the excess voltage and dissipates it to provide protection to the system.
