RailClamp is an ultra low capacitance Transient Voltage
Suppressor (TVS) designed to protect high speed data
interfaces. This device has been specifically designed to
protect sensitive components which are connected to highspeed data and transmission lines from over-voltage
caused by ESD (electrostatic discharge), CDE (Cable
Discharge Events), and EFT (electrical fast transients).
The RClampTM0531T has a maximum capacitance of only
0.80pF. This allows it to be used on circuits operating in
excess of 2.5GHz without signal attenua-tion. They may be
used to meet the ESD immunity requirements of IEC
61000-4-2.

Discharge (ESD) protection diodes in small SurfaceMounted Device (SMD) plastic packages designed
to protect one data line from the damage caused by
ESD.
