MXLSMLG85CAE3 Application Field and Working Principle

TVS-Diodes are a widely used technology for protecting sensitive electronic equipment in industry, consumer, and automotive applications. The devices are designed to protect against transient voltage spikes in high-speed signal lines due to electrostatic discharge (ESD) events or lightning surges. The MXLSMLG85CAE3 is one of the newest products in the TVS-Diode family. In this article, we will explore the application field and working principle of the MXLSMLG85CAE3.

Applications

The MXLSMLG85CAE3 is designed to provide ESD, EFT, and lightning surge protection in automotive, consumer electronics, and industrial applications. The device can be used in a variety of applications such as: Li-Ion battery packs, USB ports, Modems, Sensors, Automotive ECUs, Wireless communications, and more. It offers a good balance of clamping voltage, low capacitance, and low leakage current in order to provide maximum protection with minimal noise.

Working Principle

The MXLSMLG85CAE3 works by clamping the transient voltage spike and providing a low-impedance path from the protected device to ground. It features a Zener diode and a series-connected transistor, as well as a metal-oxide varistor (MOV) for surge protection. When the input voltage exceeds the breakdown voltage of the Zener diode, current flows through the Zener diode and diode switch assembly, turning on the transistor. This diverts current away from the protected device and into the ground. The MOV acts as a “last line of defence” by absorbing the surge energy and then dissipating it as heat.

The MXLSMLG85CAE3 also features a thermal fusing element which protects against repeated over-voltage events. When a high current flows through the device for an extended period of time, the thermal element will open, shutting off current flow and preventing additional damage to the protected device.

Conclusion

In conclusion, the MXLSMLG85CAE3 is an ideal choice for applications requiring ESD, EFT, or lightning surge protection. It offers a wide range of features, such as low capacitance, low leakage current, and a thermal fusing element for repeated over-voltage events.
