SRDA12-4.TBT

The SRDA12-4 RailClamps are surge rated diode arrays designed to protect high speed data interfaces.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 SRDA12-4 may be used on lines operating up to 12 volts .SRDA12-4 are in a 8-pin SOIC package. 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.
