3 Description

ESD752 is a bidirectional ESD protection diode for

Controller Area Network (CAN) interface protection.

ESD752 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

ESD752 is suitable for CAN, CANFD, CAN SiC, and

CAN-XL applications that can support data rates up to

20Mbps.
