RClamp2574NQ  
High Power TVS for  
Ethernet Interfaces  
PROTECTION PRODUCTS - RailClamp®  
Description  
Features  
RailClamp® TVS diodes are specifically designed to  
protect sensitive components which are connected to  
high-speed data and transmission lines from overvolt-  
age caused by ESD (electrostatic discharge), CDE  
(cable discharge events), and EFT (electrical fast  
transients).  
‹ Transient protection for high-speed data lines to  
IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact)  
IEC 61000-4-4 (EFT) 40A (5/50ns)  
IEC 61000-4-5 (Lightning) 40A (8/20µs)  
‹ Array of surge rated diodes with internal TVS Diode  
‹ Small package saves board space  
‹ Protects two line pairs  
‹ Low capacitance for high-speed interfaces  
‹ Low variation in capacitance vs. bias voltage  
‹ Low clamping voltage  
The unique design incorporates surge rated, low  
capacitance steering diodes and a TVS diode in a  
single package. The RClamp®2574NQ is designed to  
replace up to two components for board level GbE  
protection. Each device is designed to protect two line  
pairs. This is accomplished by routing traces through  
the device. When connected in this fashion, the  
device can withstand a high level of surge current  
(40A, 8/20us) while maintaining a low loading capaci-  
tance of less than 5pF. The high surge capability  
means it can be used in high threat environments in  
applications such as Gigabit Ethernet, telecommunica-  
tion lines, and LVDS interfaces.  
The RClamp®2574NQ 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. It features a true operat-  
ing voltage of 2.5 volts for superior protection.  
‹ Qualified to AEC-Q100 Grade1  
‹ Solid-state silicon-avalanche technology  
Mechanical Characteristics  
‹ SLP3020N10 10L package  
‹ Pb-Free, Halogen Free, RoHS/WEEE Compliant  
‹ Nominal Dimensions: 3.0 x 2.0 x 0.60 mm  
‹ Lead Finish: NiPdAu  
‹ Molding compound flammability rating: UL 94V-0  
‹ Marking : Marking code + Date code  
‹ Packaging : Tape and Reel  
Applications  
‹ 10/100/1000 Ethernet  
‹ Central Office Equipment  
‹ LVDS Interfaces  
‹ MagJacks / Integrated Magnetics  
‹ Notebooks / Desktops / Servers  
The RClamp2574NQ is in a 10-pin SLP3020N10  
package. It measures 3.0 x 2.0 x 0.60mm. The leads  
are finished with lead-free NiPdAu.  
RClamp®2574NQ is qualified to AEC-Q100 Grade 1.
