RClamp7534F Low Capacitance TVS for LVDS Interfaces PROTECTION PRODUCTS - RailClamp® Description Features Transient protection for high-speed data lines to RailClamp® TVS diode arrays are specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. This allows the device to absorb large amounts of energy while protecting downstream components from harmful transient events. The RClamp7534F is in a 6-pin SC-70 package. The leads are finished with lead-free matte tin. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). The combination of small size, low capacitance, and high ESD surge capability makes them ideal for use in applications such as next generation color LCD displays and LVDS interfaces.

When the voltage on the protected line exceeds the breakdown voltage of the internal TVS diode, the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry to ground. Data lines are connected at pins 1, 3, 4 and 6. Pin 2 should be connected directly to a ground plane. The path length is kept as short as possible to minimize parasitic inductance. An external 10 Ohm resistor can be added as shown. This helps restrict the flow of ESD current further enhancing the circuit protection capability of the device. When configured as shown, a LVDS chip may withstand up to 10A for a 2/10 us impulse waveform. © 2010 Semtech Corp.
