The 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 Gigabit Ethernet (GbE). Its ultra-low capacitance of 1.7 pFminimizes signal degradation on each channel.
The expanded adoption of sensor-based and Internet-of-Things (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 electrostatic discharge (ESD) and surge damage, and therefore, require robust protection. Bourns’ 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.
The diode array combines a 2.5V TVS diode with steering diodes to provide protection for eight high-speed data lines. It also meets specified safety standards providing ±30 kV contact and discharge ESD protection according to IEC 61000-4-2, and 45A (8/20 μsec) IEC 61000-4-5 lightning protection.
