The products described herein and this document are subject to specific legal disclaimers as set forth on the last page of this document, and at www.bourns.com/docs/legal/disclaimer.pdf. ## **CDSOT23-T24CAN CANbus Protector** ## ~~**Application Information**~~ The Model CDSOT23-T24CAN dual TVS diode array is designed to protect a CANbus transceiver against surge events per IEC 61000-4-5 (Level 1), and also increase the resistibility against ESD events beyond IEC 61000-4-2 to as high as 30 kV. It is intended to be used with a transceiver that has internal protection against other faults such as 24 V power supply miswiring. The Model CDSOT23-T24CAN is designed with a minimum breakdown voltage of 26.2 V so that it will not conduct during a 24 VDC power cross event. The surge test setup below shows the differential input/output (I/O) of a typical transceiver, its termination network, being protected by the CDSOT23-T24CAN device. The 1.2/50 μs voltage, 8/20 μs current combination wave generator is connected to the circuit through two 80 ohm resistors and a coupling device (CD). This circuit was subjected to a 500 V (1.2/50) longitudinal surge (common mode) in both positive and negative polarities per IEC 61000-4-5 (Level 1). The oscilloscope traces in Figures 1 and 2 show the clamp voltage with respect to ground for the CAN H and CAN L signal lines, as well as the total surge current output from the surge generator into the circuit, for each of these surges. The peak current on each line is ~ 5.5 A (11 A total/2 lines) when subjected to the 500 V (1.2/50) surge. The TVS diode clamps the voltage at the I/O of the transceiver within 37 V during the surge. **==> picture [192 x 89] intentionally omitted <==** **----- Start of picture text -----**

_Figure 1 - CDSOT23-T24CAN Clamp Voltages for a +500 V Surge_ _Figure 2 - CDSOT23-T24CAN Clamp Voltages for a -500 V Surge_ Specifications are subject to change without notice. Users should verify actual device performance in their specific applications. The products described herein and this document are subject to specific legal disclaimers as set forth on the last page of this document, and at www.bourns.com/docs/legal/disclaimer.pdf. ## **CDSOT23-T24CAN CANbus Protector** ## ~~**Layout Considerations**~~ The figure below shows an example of how the Model CDSOT23-T24CAN can be connected on a two-sided PCB design ~~.~~ The device should be placed as close to the bus connector as possible with short traces to the signal lines. Since the connector pin spacing is generally much larger than the pin spacing of the transceiver, it is relatively easy to do this. A standard 10 mil, 1 ounce copper trace is more than adequate to handle the peak current level from the 500 V surge discussed in the previous section. The ground pin of the device should be connected to the circuit board ground plane using a short trace and a via. If there is a ground plane on the signal side of the circuit board near where the diode array is placed, it should be connected directly to it. ## ~~**Typical Part Marking**~~ **==> picture [136 x 54] intentionally omitted <==** **----- Start of picture text -----**
