V3.5MLA0805NT

TVS (Transient Voltage Surge Suppressor) devices, including varistors, MOVs, and other components offer a reliable source of protection for circuits and systems that can be damaged by brief, high-voltage surge events. The V3.5MLA0805NT is one of these TVS devices that is specifically designed for 10/100Base-T LAN/data communication applications. It provides a low-capacitance, low-signal line protection for high-speed data lines to help protect against transient voltage events, from both internal and external sources. This article will provide an overview of the V3.5MLA0805NT application field and its working principle.

Application Field

The V3.5MLA0805NT is designed for 10/100Base-T LAN/data communication applications. It works as a low-capacitance, low-signal line suppression device, which is ideal for high speed data transmission protection. Its 8uH capacitance is perfectly suited for Ethernet applications, allowing for fast and error-free data transmission and reception. High speed transmission lines in noisy industrial, auto, and telecom environments also benefit from the protection provided by the V3.5MLA0805NT.

Working Principle

The V3.5MLA0805NT is a two-port device that is comprised of an emitter and a collector. The emitter is connected to the ground of the circuit, while the collector is connected to the signal line. The device works by monitoring the voltage on the signal line and detecting when it exceeds a predetermined threshold. If the voltage on the signal line exceeds the threshold, the device triggers a current conduction effect in the form of an avalanche breakdown. This creates an avalanche of additional electron and hole carriers, reducing the voltage on the signal line and protecting it from damage.

The V3.5MLA0805NT also offers surge protection on both the positive and negative side of the signal line. When the negative side of the signal line exceeds the threshold, the device triggers a reverse bombardment effect, where current is also conducted in the opposite direction, lowering the voltage on the negative side.

The V3.5MLA0805NT is also equipped with a low clamping voltage of 9.2V, which allows it to handle high-energy transients and provide over-voltage protection. It is also designed such that it will not adversely affect signal integrity, helping to ensure that the signal remains transparent and noise-free.

Conclusion

The V3.5MLA0805NT is a low-signal line protection device specifically designed for 10/100Base-T LAN/data communication applications, providing surge protection on both the positive and negative side of the signal line. It has an 8uH capacitance that is perfectly suited for Ethernet applications and a low clamping voltage of 9.2V that makes it ideal for high-energy transients. With these features, the V3.5MLA0805NT is well-suited for use in industrial, auto, and telecom environments.
