The RailClamp SRDA series low capacitance TVS Diode Array designed to protect high speed data interfaces. The device is specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by electrostatic discharge ESD, electrical fast transients EFT and lightning. During transient conditions, the steering diodes direct the transient current to ground via the internal low voltage TVS. The 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. It 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. The high surge capability Ipp=25A, tp=8/20µs means it can be used in high threat environments in applications.
