RClamp0534N

Low Capacitance TVS for High-Speed Interfaces PROTECTION PRODUCTS - RailClamp® Description

Features ‹ ESD protection for high-speed data lines to

RailClamp® TVS diodes 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 RClamp®0534N is in a 10-pin SLP3020N10 package. It measures 3.0 x 2.0 x 0.60mm. The leads are finished with lead-free NiPdAu. The combination of small size, low capacitance, and high surge capability makes them ideal for use in applications such as 10/ 100 Ethernet, USB 2.0, and video interfaces.

RClamp0534N PROTECTION PRODUCTS Applications Information Figure 1- Pin Configuration (Top View)

Device Connection Options for Protection of Four High-Speed Data Lines The RClamp0534N is designed to protect four data lines from transient over-voltages by clamping them to a fixed reference. When the voltage on the protected line exceeds the reference voltage (plus diode VF) the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry. Data lines are connected at pins 1, 2, 4 and 5. The package is designed for easy trace routing. Pins 3 and 8 are internally connected to the center tabs and should be connected directly to a ground plane on the board for best results. The path length is kept as short as possible to minimize parasitic inductance. The positive reference (REF2) is connected at pin 9. The options for connecting the positive reference are as follows:

I/0 1 In I/0 2 In

GND

1. To protect data lines and the power line, connect pin 10 directly to the positive supply rail (VCC). In this configuration the data lines are referenced to the supply voltage. The internal TVS diode prevents over-voltage on the supply rail. 2. The RClamp0534N can be isolated from the power supply by adding a series resistor between pin 10 and VCC. A value of 100kΩ is recommended. The internal TVS and steering diodes remain biased, providing the advantage of lower capacitance. 3. In applications where no positive supply reference is available, or complete supply isolation is desired, the internal TVS may be used as the reference. In this case, pin 10 is not connected. The steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the TVS (plus one diode drop).
