Bourns announced the release of a new ESD protection product, the Model CDDFN10-2574N, for high-speed communication port applications. The TVS (transient voltage suppressor) diode array comes in a DFN-10 package and combines a 2,5 V TVS diode with steering diodes to provide protection for eight high-speed data lines. It offers an ultra-low capacitance of only 1,7 pF from each input/output to ground and provides ±30 kV contact discharge and ±30 kV air discharge ESD protection per IEC 61000-4-2.
The device is designed to protect high-speed data ports from ESD transients. For high-speed ports such as Gigabit Ethernet, maintaining signal line impedance is a critical requirement. The use of a DFN10 package using a flow-through layout provides minimal impedance change on the high-speed data line, while the ultra-low capacitance of the device minimises signal degradation on each channel. Unlike competing technologies, the solid state avalanche technology used in the CDDFN10-2574N does not degrade after multiple ESD events.
