ESD2CAN24-Q1

The ESD2CANxx24-Q1 (wired operation) features a bidirectional ESD protection diode for Controller Area Network (CAN) interface protection. The ESD2CANxx24-Q1 dissipates contact ESD strikes beyond the maximum level specified in the ISO 10605 automotive standard (±30kV contact, ±30kV air gap). The low dynamic resistance and low clamping voltage enable system level protection against transient events. This protection provides essential capability as automotive systems require high levels of robustness and reliability for safety applications.

This device features low I/O capacitance per channel and a pinout designed to protect two automotive CAN bus lines (CANH and CANL) from damage caused by electrostatic discharge (ESD) and other transients. Additionally, the 3pF (typical) and less line capacitance of the ESD2CANxx24-Q1 supports CAN, CANFD, CAN SiC, and CAN-XL applications that can achieve data rates up to 10Mbps.
