1 www.semtech.com PROTECTION PRODUCTS SRV08-4 Low Capacitance TVS Diode Array Description Features Circuit Diagram Schematic & PIN Configuration Revision 06/25/2002 RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The SR series has been specifically designed to protect sensitive compo- nents which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), EFT (electrical fast transients), and light- ning. The unique design of the SRV08-4 integrates eight surge rated, low capacitance steering diodes with a TVS diode in a SOT23- 6L package. 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 compo- nents. The low capacitance array configuration allows the user to protect four high-speed data or transmission lines. The low inductance construction minimizes voltage overshoot during high current surges.
