SEMTECH RCLAMP2504N.TCT

A RailClamp® is a low capacitance TVS array designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and Lightning. 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 to ground. The internal TVS diode clamps the transient voltage to a safe level. The low capacitance array configuration allows the user to protect up to four high-speed data lines. The RClamp®3304N and RClamp®2504N are 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. They feature a true operating voltage of 2.5 volts and 3.3 volts for superior protection. These devices are in a 10-pin, RoHS/WEEE compliant, SLP2626P10 package. The high surge capability (10p = 25A, tp = 8/20μs) means it can be used in high threat environments in applications such as Gigabit Ethernet, telecommunication lines, and digital video.
