General Information The Model CDSOT23-T24CAN device is designed to provide ESD and surge protection for CAN transceivers, meeting IEC 61000-4-2 (ESD) and IEC 61000-4-5 (Surge) requirements. The dual TVS array protects both data lines, offers a Working Reverse Voltage 24 V and a Minimum Breakdown Voltage 26.2 V and can be used with transceivers with internal circuitry for 24 V power supply miswiring. The low capacitance and low leakage current of the Model CDSOT23-T24CAN minimizes impact on signal integrity and is compatible with high-speed CAN. The SOT-23 packaged device conforms to JEDEC standards and will mount directly onto the industry standard SOT-23 footprint. Its compact size eases layout on compact PCB designs while ensuring compliance with stringent EMI requirements. Absolute Maximum Ratings 25 C Unless Otherwise Noted)

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 to as high as 30 kV. It is intended to be used with a transceiver that has internal protection against other faults such 24 V power supply miswiring. The Model CDSOT23-T24CAN is designed with a minimum breakdown voltage 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 s voltage, 8/20 s current combination wave generator is connected to the circuit through two 80 ohm resistors and a coupling device (CD). This circuit was subjected 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 A total/2 lines) when subjected to the V (1.2/50) surge. The TVS diode clamps the voltage at the I/O of the transceiver within 37 V during the surge.
