Features Applications Single device for two I/O lines High-speed CANbus Low capacitance for high-speed CANbus Industrial control networks IEC 61000-4-2 30 kV ESD Smart Distribution Systems (SDS) IEC 61000-4-5 (Level 1, CWG 1.2/50) DeviceNet 500 V Surge Factory and process automation systems RoHS compliant* AEC-Q101 compliant** CDSOT23-T24CAN-Q CANbus Protector General Information The Model CDSOT23-T24CAN-Q 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 1 Reverse Voltage of 24 V and a Minimum Breakdown Voltage of 26.2 V and can be used with transceivers with internal circuitry for 24 V power supply miswiring. The low capac- 3 itance and low leakage current of the Model CDSOT23-T24CAN-Q minimizes impact on signal integrity and is compatible with high-speed CAN. 2 The SOT-23 packaged device 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.
