RCLAMP2502L.TBT

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 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 RClamp2502L is constructed using 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 for superior protection.The RClamp2502L is in a 8-pin SOIC package. The leads are finished with lead-free matte tin. The combination 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.
