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.

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. To Next Connection Figure 2.

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.
