RCLAMP2574N.TCT

RailClamp TVS diodes are specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients).The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. The RClamp2574N 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 capacitance of less than 5pF. The high surge capability means it can be used in high threat environments in applications such as Gigabit Ethernet, telecommunication lines, and LVDS interfaces.The RClamp2574N is constructed using proprietary EPD process technology. The EPD process provides low stand-off voltages with significant reductions in leakage current and capacitance over silicon avalanche diode processes. It features a true operating voltage of 2.5 volts for superior protection. The RClamp2574N 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.
