CDDFN10-2574N - Surface Mount TVS Diode Array

General Information
The Model CDDFN10-2574N device provides Electrostatic Pin 1 Pin 4
Line 1 In Line 3 In
Discharge (ESD), Electrical Fast Transients (EFT), Lightning,
and Cable Discharge Event (CDE) protection for high-speed
data ports, meeting IEC 61000-4-2 (ESD) requirements.
The Transient Voltage Suppressor array, protecting up to four
data lines, offers a Working Peak Reverse Voltage of 2.5 V and Pin 10 Pin 7
a Minimum Breakdown Voltage of 3 V. Line 1 Out Line 3 Out
Pin 2 Pin 5
The DFN10 packaged device has a low typical capacitance of Line 2 In Line 4 In
only 1.7 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
Pin 9 Pin 6
high-speed data lines. Line 2 Out Line 4 Out

Reference Application
The Bourns® Model CDDFN10-2574N is designed to protect four high-speed data lines operating at 2.5 volts from system ESD/EFT/Lightning
pulses. The use of a DFN10 package using a “feed-through” layout provides minimal impedance change on the high-speed data line, while the
low capacitance performance of the device limits signal degradation on each channel.
