3 Description
ESD2CANFD24W-Q1 is a bidirectional ESD protection diode for Controller Area Network (CAN) interface protection. ESD2CANFD24W-Q1 is rated to dissipate contact ESD strikes specified in the ISO 10605 automotive standard. 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 2pF (typical) line capacitance of ESD2CANFD24W-Q1 is designed for CAN, CANFD, CAN SiC, and CAN-XL applications that can support data rates up to 10Mbps.
