TVS are highly reliable, high power devices used for the purpose of preventing electrical damage to sensitive equipment from electrostatic discharge, caused by sparks or other events. There are many different types of TVS, ranging from transient voltage suppressor (TVS) diodes to integrated circuits (ICs). The LCDA05.TBT is one of the most popular TVS diodes in the market today. Developed by Littelfuse, the device is designed specifically to offer significant protection for data lines from high-voltage increases or spikes.

The LCDA05.TBT is a low-capacitance, dual-channel termination ESD protection diode, designed to protect against ElectroStatic Discharge (ESD) events. This highly reliable diode is an ideal solution for protecting sensitive data lines, such as high-speed USB and HDMI, from damage caused by ESD-related voltage overshoots. The LCDA05.TBT integrates two TVS diodes in a surface-mount package, providing excellent low-profile protection for data lines.

The LCDA05.TBT provides ESD protection by clamping the voltage of the protected line to the protection voltage level of 18V for IEC level 4, or 30V for IEC level 3. This prevents overvoltage caused by ESD strikes from entering the protected line. The device also incurs a low capacitance load of 8pF per channel, helping to minimize data line signal distortion. In addition, this low capacitance provides protection from ESD strikes with rise times as low as 5ns.

The LCDA05.TBT is designed using a robust electro-conductive dielectric package, which provides excellent thermal and electrical protection. The device also includes an innovative built-in thermal fuse that trips when temperatures rise to 110°C, providing additional protection from thermal overloads. The LCDA05.TBT is compatible with lead-free soldering processes, such as reflow and wave soldering, and is designed to have a maximum reflow temperature of +260°C.

The LCDA05.TBT is well-suited for data line protection applications requiring high reliability and excellent signal clarity. It is used in a variety of applications, including notebook and desktop computers, as well as consumer electronic products and industrial equipment. The device is available in both tape-and-reel and tube packaging for easy integration into standard production lines.

In summary, the LCDA05.TBT is a highly reliable dual-channel termination ESD protection diode, designed to offer significant protection from electrical damage caused by electrostatic discharges. Its robust package and low capacitance provide excellent thermal and electrical protection, while its built-in thermal fuse offers additional protection from thermal overvoltage. The device is available in both tape-and-reel and tube packaging, making it easy to integrate into standard production lines.
