New TVS diode array maintains critical signal line impedance for IoT-enabled applications

Bourns has introduced a TVS diode array designed to provide effective surge protection in high-speed communication port and sensitive transceiver applications. The Bourns Model CDDFN10-2574N TVS diode array features a DFN10 package that uses a flow-through layout to enable minimal impedance change, which is a critical requirement for high-speed ports such as GbE. Furthermore, its ultra-low capacitance of only 1.7 picofarads minimizes signal degradation on each channel. The expanded adoption of sensor-based and IoT applications will continue to depend upon GbE and other high-speed lines. When these connected devices are deployed in remote, harsh environment locations, they are particularly susceptible to ESD and surge damage, and therefore, require robust protection. Offering a superior performance solution, their latest TVS diode array offers lower clamp voltage on surge, and unlike competing technologies, it uses solid-state avalanche technology that does not degrade after multiple ESD events.
