Product Brief
Low-clamping protection array targets fast-growing Ethernet market
Julien Happich2/4/2010 4:12 AM EST
The device safeguards Fast Ethernet and Gigabit Ethernet interfaces from electrostatic discharge (ESD), cable discharge and lightning surge transients.
The two-line RClamp 2502L delivers optimal transient protection, featuring a very low clamping voltage and a line-to-line capacitance of less than 5pF.
The part's robust (40A, tp=8/20 microsecond) surge rating for secondary lightning protection meets the industry's stringent telecommunications surge requirements.
Additionally, the flow-through layout of the part contributes to enhanced signal quality and ease in PCB routing.
As Ethernet transceivers migrate to smaller geometries, low working voltage and low capacitance protection becomes critical to achieving a high transient protection margin without adversely compromising signal-integrity.
The RClamp 2502L device is a drop-in replacement for SO-8 TVS arrays in communication systems that employ previous generation 5V working voltage TVS protection, but now need the improved clamping and transient response time performance.
