TVS (Transient Voltage Suppressor) and Varistors (“Variable resistors”) are one of the most common components in electronics industry. These components have a wide range of applications, including protection of power supplies, protection of data lines, and filtering of transients. The MLV1206E34503T is an example of both a TVS and a Varistor. This application field and working principle will be explored in further detail in the following article.

MLV1206E34503T Application Field

The MLV1206E34503T component is designed for use in a variety of applications in the electronics industry. It is primarily used for overvoltage protection on data lines, differential signaling, and power supplies. It is also commonly used in high-speed signal transmission applications for signal isolation or spike suppression. Additionally, due to its ability to handle high power switching applications, the MLV1206E34503T can be used in controlling the power supply current from a steady voltage source.

MLV1206E34503T Working Principle

The operation of the MLV1206E34503T is primarily based on the principle of electrostatic protection. The component works by detecting excessive voltage on the power line and diverting it away from the vulnerable circuit elements. To achieve this, the component contains an absorbed-gas metal oxide varistor (MOV) together with an integrated E-type clamp. The MOV works by absorbing and dissipating the voltage from the power line through its breakdown voltage, while the integrated E-type clamp provides additional protection by clamping the voltage to the ground. This helps prevent further damage to the circuit elements from the excessive voltage.

The MLV1206E34503T is designed to provide an open-circuit detection voltage of 1.10 V, and its maximum breakdown voltage is 34 V. The component also operates at a temperature range of - 40°C to + 85°C. In addition, the component is designed for surface-mounting and has a footprint compatible with most leadless packages.

Conclusion

To summarise, the MLV1206E34503T is a component used in the electronics industry mainly for overvoltage protection on power lines, differential signaling, and power supplies. The component utilises an absorbed-gas metal oxide varistor (MOV) together with an integrated E-type clamp to provide electrostatic protection against excessive voltage. The component is designed for surface-mounting with a compatible leadless footprint and operates at a temperature range of - 40°C to + 85°C.
