3 Description

The ESD2CANFD24 is a bidirectional ESD protection

diode for Controller Area Network (CAN) interface

protection. The ESD2CANFD24 is rated to dissipate

contact ESD strikes beyond the maximum level

specified in the IEC 61000-4-2 standard (±25-kV

Contact, ±25-kV Airgap). The low dynamic resistance

and low clamping voltage enables system level

protection against transient events. This protection is

key as 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 2.5 pF (typical) or less line capacitance of the

ESD2CANFD24 is suitable for CAN, CANFD, CAN

SiC, and CAN-XL applications that can support data

rates up to 10 Mbps.

The ESD2CANFD24 is offered in a leaded package

for easy flow through routing.
