Description

RailClamps® are low capacitance TVS arrays designed

to protect high speed data interfaces. This series

has been specifically designed to protect sensitive

components which are connected to high-speed data

and transmission lines from over-voltage caused by ESD

(electrostatic discharge), CDE (Cable Discharge Events),

and EFT (electrical fast transients).

RClamp®0554T has a typical capacitance of only 0.28pF

between I/O pins. They may be used to meet the ESD

immunity requirements of IEC 61000-4-2. Each device is

designed to protect four lines (two differential pairs).

RClamp0554T is in a DFN 2.0x1.0x0.4mm 10-Lead

package. They are designed for easy PCB layout by

allowing the traces to run straight through the device.

The combination of small size, low capacitance, and high

level of ESD protection makes them a flexible solution for

applications such as mini HDMI, MDDI, USB, and eSATA

interfaces.
