RCLAMP0504N.TCT

Rail Clamps are surge rated diode arrays designed to protect high speed data interfaces. The RClamp 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 of the RClamp series devices incorporates eight surge rated, low capacitance steering diodes and a TVS in a single 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 components. The RClamp0504N has a low typical capacitance of 3pF and operates with virtually no insertion loss to 1GHz. This makes the device ideal for protection of high-speed data lines such as USB 2.0, Fire wire, DVI, and gigabit Ethernet interfaces. The RClamp0504N is in a 6-pin, RoHS compliant, SLP2020P6 package. It measures 2.0 x 2.0 x 0.60mm. The leads are spaced at a pitch of 0.5mm and are finished with lead-free NiPdAu. Each device may be used to protect four high-speed data or transmission lines. They may be used to meet the ESD immunity requirements of I EC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).
