SR70  
RailClamp  
Low Capacitance TVS Diode Array  
PROTECTION PRODUCTS  
Features  
Description  
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.  
‹ Transient protection for high speed data lines to  
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)  
IEC 61000-4-4 (EFT) 40A (5/50ns)  
IEC 61000-4-5 (Lightning) 1kV, 24A (8/20µs)  
‹ Array of surge rated, low capacitance diodes  
‹ Protects two I/O lines  
‹ Low capacitance (5pF typical) for 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.  
‹ Low clamping voltage  
‹ Solid-state silicon-avalanche technology  
Mechanical Characteristics  
‹ JEDEC SOT-143 package  
‹ UL 497B listed  
‹ Molding compound flammability rating: UL 94V-0  
‹ Marking : R70  
‹ Packaging : Tape and Reel per EIA 481  
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 (VF) above the supply (reference) voltage. The  
SR70 may be used as a stand alone device or in  
conjunction with TVS diodes for enhanced protection.  
Applications  
‹ ADSL Lines  
‹ I2C Bus Protection  
‹ Video Line Protection  
‹ T1/E1 secondary IC Side Protection  
‹ Portable Electronics  
‹ Microcontroller Input Protection  
‹ WAN/LAN Equipment  
‹ ISDN S/T Interface
