The Transient Voltage Suppressor array, protecting up to four data lines, offers a Working Peak Reverse Voltage of 3.3 V and a Minimum Breakdown Voltage of 4.5 V. The DFN1 packaged device has an ultra-low typical capacitance of only.4 pf between I/O lines. This allows it to be used for protecting sensitive components used on high-speed interfaces. The small footprint of the device allows for flow-through routing on the PCB, helping to maintain matched impedances of the high-speed data lines.

4 CDDFN1-3324P - Surface Mount TVS Diode Array Reference Application The Bourns Model CDDFN1-3324P is designed to protect high-speed data ports from ESD transients. For high-speed ports above 5 Gbps such as HDMI 2. and USB 3., maintaining signal line impedance is a critical requirement. The use of a DFN1 package using a feedthrough layout provides minimal impedance change on the high-speed data line, while the ultra-low capacitance performance of the device limits signal degradation on each channel.
