Applications Information
Device Connection Options for Protection of Four
High-Speed Data Lines
The RClamp0504M TVS 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 V F ) the steering diodes are forward biased,
conducting the transient current away from the
sensitive circuitry.

The RClamp0504M is designed for have ease of PCB
layout by allowing the traces to run straight through the
device. Figure 1 shows the proper way to design the PCB
board trace in order to use the flow through layout for
two line pairs. The solid line represents the PCB trace.
Note that the PCB traces are used to connect the pin

pairs for each line (pin 1 to pin 10, pin 2 to pin 9, pin 4
to pin 7, pin 5 to pin 6). For example, line 1 enters at
pin 1 and exits at Pin 10 and the PCB trace connects pin
1 and 10 together. This is true for lines 2, 3, and 4. The
negative reference (Gnd) is connected at pin 8. This pin
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 is connected at pin 3. The options for
connecting the positive reference are as follows:

3 directly to the positive supply rail (V CC ). In this
configuration the data lines are referenced to the
supply voltage. The internal TVS diode prevents
over-voltage on the supply rail.
2. In applications where no positive supply reference is
available, or complete supply isolation is desired,
figure 3 shows how the internal TVS may be used as

the reference. In this case, pin 3 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).
This ease of layout coupled with the low capacitance and
clamping voltage of the RClamp0504M makes it the
superior choice to protect two high speed line pairs.
