Revision 04/18/03
RailClamps are surge rated diode arrays designed to
protect high speed data interfaces. The SR70 has
been specifically designed to protect sensitive compo-
nents which are connected to data and transmission
lines from over-voltages caused by ESD (electrostatic
discharge), EFT (electrical fast transients), and light-
ning. The SR70 has been optimized for use on ADSL
and other high-speed interfaces.
The unique design of the SR70 integrates four surge
rated, low capacitance steering diodes in a low profile
SOT-143 package. It has a typical capacitance of only
5pF and may be used to protect two high-speed lines
without sacrificing signal integrity. The SR70 is de-
signed to replace “standard” rectifiers that are not
rated for the high energy surges that are normally
expected in telecommunications applications.
During transient conditions, the steering diodes direct
the transient to either the positive side of the power
supply line or to ground. The maximum clamping
voltage seen by the protected circuit will be one diode
drop (V
F) above the supply (reference) voltage.
The
SR70 may be used as a stand alone device or in
conjunction with TVS diodes for enhanced protection.
