3 Description

ESD2CAN24W-Q1 is a bidirectional ESD protection diode for Controller Area Network (CAN) interface protection. ESD2CAN24W-Q1 is rated to dissipate contact ESD strikes specified in the IEC 61000-4-2 standard. The low dynamic resistance and low clamping voltage enables system level protection against transient events. This protection is key as industrial 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 CAN bus lines (CANH and CANL) from the damage caused by ElectroStatic Discharge (ESD) and other transients. Additionally, the 3pF (typical) line capacitance of ESD2CAN24WQ1 is suitable for CAN, CANFD, CAN SiC, and CANXL applications that can support data rates up to 20Mbps.
