ESD2CAN24DCKRQ1

The ESD2CANxx24-Q1 is a bidirectional ESD protection diode for Controller Area Network (CAN) interface protection. The ESD2CANxx24-Q1 is rated to dissipate contact ESD strikes beyond the maximum level specified in the ISO 10605 automotive standard (±30-kV Contact, ±30-kV Airgap). The low dynamic resistance and low clamping voltage enables system level protection against transient events. This protection is key as automotive systems require a high level of robustness and reliability for safety applications. This device features 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. Additionally, the 3 pF (typical) or less line capacitance of the ESD2CANxx24-Q1 is suitable for CAN, CANFD, CAN SiC, and CAN-XL applications that can support data rates up to 10 Mbps. The ESD2CANxx24-Q1 is offered in two leaded packages for easy flow through routing.
