The semiconductor television diode TLP28CA is an overvoltage protection device that provides a low-level bidirectional overvoltage protection function. TVS diodes, more commonly known as transil diodes, are used in a variety of applications such as automotive, high-speed data and signal lines, and consumer electronics. TLP28CA is a typical member of this family that is widely used in applications such as servers, network protection, and telecom equipment. TLP28CA consists of a double-diffused, high voltage avalanche diode with a current rating which is created using diffusion technology. The overvoltage protection function is achieved by the integrated overvoltage protection breakdown mechanism. The internal built-in bipolar transistor has a negative temperature coefficient. By utilizing this feature, TLP28CA can effectively protect the system components from overvoltage conditions. The working principle of TLP28CA is relatively simple. The overvoltage protection device is constructed in such a way that the current flow is limited when a certain voltage is applied. This is accomplished by two main functions. First, a competing path by a capacitive element is activated, thus reducing the current flow. Second, a physical breakdown process occurs in which the voltage is increased and the internal breakdown voltage is applied across the device. Once this process occurs, the current is limited. TLP28CA is used in a variety of applications such as servers, network protection, and telecom equipment, due to its low-level bidirectional overvoltage protection. It is capable of handling high energy and voltage spikes that can be caused by power surges, lightning, or electromagnetic interference. Since it is designed to protect against overvoltage, it can also be used in applications that require voltage limiting or protection against negative transients. With a maximum continuous operating voltage of 400V, it is an ideal device to protect against very high voltage overvoltages. To further enhance the reliability and protection capability, the device also features a non-polar configuration, which is ideal for applications that require bidirectional overvoltage protection. In the future, it is expected that the use of TLP28CA will continue to grow, due to its versatility and protection capabilities. Its low-level bidirectional overvoltage protection is essential in protecting valuable systems and components from destruction due to dangerous voltage spikes. As technology continues to evolve, its use is expected to expand even further. Overall, the TLP28CA is an essential device for providing overvoltage protection in a variety of applications. Its low-level bidirectional protection is essential for protecting valuable systems and components from destruction due to dangerous voltage spikes. Its non-polar configuration further enhances the reliability and protection capabilities, making it ideal for applications that require bidirectional overvoltage protection. Its continuous operating voltage of 400V makes it an excellent device for high voltage overvoltages.
