CDSOT236-DSL03xx - TVS Diode Array Series
Application Information
Communication systems with exposed signal lines are often subjected to high level transient threats. The CDSOT236-DSL03xx
family of devices was designed to help protect signal lines from
threats such as those defined in Telcordia GR-1089 and ITU-T.
Figure 1 shows the CDSOT236-DSL03xx TVS diode array used
in a design topology that protects a VDSL driver. The diode
array limits the peak differential voltage across the VDSL driver
outputs. The current limiting resistors (RP), typically about 1 ohm,
limit the peak current seen by the driver. Low voltage varistors
MOV1 and MOV2, with a typical working voltage of less than
20 V, limit the current in the line side of the transformer by limiting
the voltage across it. Exact values for the current limiting resistors
and the varistors are dependent on the characteristics of the
transformer as well as the sensitivity of the driver to overvoltage/
overcurrent conditions. The use of primary protectors downstream from the device will also influence the requirements for
this protection circuit design. In applications sensitive to very low
levels of leakage current, optional bias resistors RB1 and RB2
can be used. Both resistors would be required for dual supply
applications. Only RB1 is required for single supply applications.
In this case, the anodes of the diode array should be connected
to ground.

Figure 1. VDSL Driver Protection Design Topology
When routing differential signal traces on the PCB, such as in a
VDSL application, it is important to maintain symmetry in the
routing. Figure 2 below shows an example of how differential
traces that connect to the CDSOT236-DSL03xx TVS diode array
can be routed. As the signal traces approach the diode array
From IC
the traces should be flared out to make the connections with the
device and then brought back together on the opposite side of
the device. Routing to the next destination would continue from
there.

CDSOT236-DSL03xx - TVS Diode Array Series
Application Information (Continued)
In applications where the current limiting resistors (RP in
Figure 1) cannot reduce the current into (or out of) the driver to
an acceptable level, the resistors can be replaced with a Bourns®
Transient Current Suppressor (TCS™) device as shown in
Figure 3. The Model TCS-DL004-750-WH shown in Figure 3 is a
dual channel device that has a nominal series resistance of only
1 ohm. The resistance between the two channels is very well
matched with a nominal maximum difference of + 0.02 ohms
between the channels. This device has a nominal trigger current
of 1.1 amps. The current through the device would be limited to
this level with up to 40 V across this device, making it dramatically more effective than a 1 ohm series resistor. Devices with
different trigger levels and series resistances are also available.
For additional information on the TCS™ family of devices, please
