RailClampÂ® Low Capacitance TVS Diode Array
RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SRDA series has been 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.
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 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. The SRDA05-4 may be used to protect lines operating up to 5 volts while the SRDA12-4 may be used on lines operating up to 12 volts.
These devices are in a 8-pin SOIC package. They are available with a SnPb or RoHS/WEEE compliant matte tin lead finish. The high surge capability (Ipp=25A,tp=8/20μs) means it can be used in high threat environments in applications such as CO/CPE equipment, telecommunication lines, and video lines.
