3 Description

The ESD2CAN24-Q1 is a bidirectional ESD protection

diode for Controller Area Network (CAN) interface

protection. The ESD2CAN24-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 ensures 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 line capacitance of

the ESD2CAN24-Q1 is suitable for CAN, CANFD,

CAN SiC, and CAN-XL applications that can support

data rates up to 10 Mbps.

The ESD2CAN24-Q1 is offered in two leaded

packages for easy flow through routing.
