Texas Instruments ESD2CANxx24/ESD2CANxx24-Q1 ESD Protection Diodes

Texas Instruments ESD2CANxx24/ESD2CANxx24-Q1 Automotive 2-Channel ESD Protection Diodes are bidirectional and created for Controller Area Network (CAN) interface protection. The ESD2CANxx24/ESD2CANxx24-Q1 is rated to dissipate contact ESD strikes beyond the maximum level specified in the ISO 10605 automotive standard (±30kV Contact, ±30kV Airgap). Low dynamic resistance and clamping voltage enable system-level protection against transient events. This protection is vital as automotive systems require high robustness and reliability for safety applications.

The TI ESD2CANxx24/ESD2CANxx24-Q1 Automotive diodes offer a low IO capacitance per channel and a pin-out to suit two automotive CAN bus lines (CANH and CANL) from the damage caused by ElectroStatic Discharge (ESD) and other transients. Furthermore, the 3pF (typical) or less line capacitance of the ESD2CANxx24/ESD2CANxx24-Q1 is suitable for CAN, CAN FD, CAN SiC, and CAN-XL applications that can support data rates up to 10Mbps.

The ESD2CANxx24/ESD2CANxx24-Q1 is housed in two leaded packages for easy flow-through routing.
