3 CDDFN-N - TVS/Steering Diode Array Reference Application Bourns Model CDDFN-N is designed to protect high speed data ports from ESD transients. For high speed ports above Gb/s such as USB 3., differential signalling is used where the need to keep impedance constant is a critical requirement. The use of a DFN- package using a feed through layout provides a minimum impedance change on the high speed while the ultra-low capacitance performance of the device limits the signal loss degradation of each channel.
