RailClamp®  
2.5V TVS for GbE Applications  
PROTECTION PRODUCTS - RailClamp®  
Features  
Description  
A RailClamp® is a low capacitance TVS array designed  
to protect high speed data interfaces. This series has  
been specifically designed to protect sensitive compo-  
nents which are connected to data and transmission  
lines from overvoltage caused by ESD (electrostatic  
discharge), CDE (Cable Discharge Events), and Light-  
ning.  
‹ 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) 24A (1.2/50μs)  
‹ Array of surge rated diodes with internal TVS Diode  
‹ Protects up to two I/O lines  
‹ Low capacitance: <5pF (Line-to-Line)  
‹ High surge capability: 40A (tp=8/20μs)  
‹ Low operating voltage: 2.5V  
The unique design incorporates surge rated, low  
capacitance steering diodes and a TVS diode in a  
single package. During transient conditions, the  
steering diodes direct the transient current away from  
the protected IC. The internal TVS diode clamps the  
transient voltage to a safe level. The low capacitance  
array configuration allows the user to protect up to two  
high-speed data lines.  
The RClamp®2502L is constructed using Semtech’s  
proprietary EPD process technology. The EPD process  
provides low stand-off voltages with significant reduc-  
tions in leakage current and capacitance over silicon-  
avalanche diode processes. They feature a true  
operating voltage of 2.5 volts for superior protection.  
‹ Easy layout  
‹ Solid-state silicon-avalanche technology  
Mechanical Characteristics  
‹ JEDEC SO-8 package  
‹ Pb-Free, Halogen Free, RoHS/WEEE Compliant  
‹ Lead Finish: Matte tin  
‹ Molding compound flammability rating: UL 94V-0  
‹ Marking : Marking Code, date code  
‹ Packaging : Tape and Reel  
Applications  
The RClamp2502L is in a 8-pin SOIC package. The  
leads are finished with lead-free matte tin. The combi-  
nation of low clamping voltage, high surge capability,  
and low loading capacitance makes the RClamp2502L  
an ideal solution for protecting GbE systems to the  
lightning immunity requirements of GR-1089.

‹ CPE Equipment  
‹ GPON Systems  
‹ VoIP Phones  
‹ Video Surveillance Systems
