RClamp®3354S Low Voltage RClamp® Surge Protection for GbE Interfaces PROTECTION PRODUCTS - RailClamp® Description Features ® u Transient protection for high-speed data lines to 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 RClamp®3354S incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. Each device will protect up to four high-speed lines. The RClamp3354S can withstand a high level of surge current (25A, 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 RClamp3354S is constructed using Semtech’s 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 low operating voltage of 3.3 volts for superior protection. The RClamp3354S is in a 5-lead SOT-23 package. The leads are finished with lead-free matte tin.
