A Transient Voltage Suppressor Diode, generally referred to as a TVS diode, is an electrical component used for protecting electrical and electronic equipment against transient overvoltages, caused by lightning or electrostatic discharges. The MSMLG85CA TVS diode is a high power, low-leakage, surface-mount device, with a maximum peak pulse power rating of 8.5A. It offers excellent ESD protection and fast response time, making it suitable for a wide range of applications.

Application of MSMLG85CA

The MSMLG85CA TVS diode is typically used in applications such as data ports, power terminals, modems, peripheral devices and other consumer electronics to protect against lightning-induced surge and ESD (Electrostatic Discharge). It can also be used in industrial, automotive, and military environments.

The device is suitable for fast overvoltage protection of data lines for ESD up to 25kV contact and up to 30kV air discharge, and for surge protection against IEC 61000-4-5 lightning events up to 8.5A. It is compliant with many industry standards including; IEC 61000-4-2(ESD) level 4, IEC 61000-4-4 with, and 8/20µs and 10/1000µs Waveforms IEC 61000-4-5 Lightning.

Working Principle of MSMLG85CA

The MSMLG85CA TVS diode is a two-terminal component that is connected in parallel with the line being protected. During normal operation, the device does not impede the signal or power. When a transient overvoltage occurs, the diode begins to conduct current and limits the voltage to a safe level, protecting the adjacent components. Its fast clamping response time provides protection from high-current, low-energy transients.

The MSMLG85CA TVS diode is equipped with a built-in voltage protection mechanism which enables it to respond quickly and safely to transient overvoltages. Once the voltage exceeds the device’s standoff voltage, the diode begins to conduct current and clamps the voltage, protecting the line and adjacent components.

The MSMLG85CA TVS diode is designed to provide maximum surge protection, without compromising response speed. It features a high peak power rating of 8.5A, and a low clamping voltage for high reliability and long-term performance. It also has a low leakage current for a more efficient operation, and a low capacitance for better signal integrity in high-speed applications.
