CDSOT23-T24CAN CANbus Protector
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) require-
ments. The dual TVS array protects both data lines, offers a Working Reverse Voltage
1
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 capacitance and low
leakage current of the Model CDSOT23-T24CAN minimizes impact on signal integrity
3
and is compatible with high-speed CAN.
The SOT-23 packaged device conforms to JEDEC standards and will mount directly
2
onto the industry standard SOT-23 footprint. Its compact size eases layout on compact
PCB designs while ensuring compliance with stringent EMI requirements.
