DESCRIPTION
RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The TVS diode is constructed using Semtech’s proprietary low voltage EPD technology for superior electrical characteristics at 2.8 volts. During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components. The low capacitance array configuration allows the user to protect two high-speed data or transmission lines. The low inductance construction minimizes voltage overshoot during high current surges.
