3 Description

The ESD2CANxx36-Q1 is a bidirectional ESD

protection diode for controller area network (CAN)

interface protection. The ESD2CANxx36-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 2.8pF (typical) or less line

capacitance of the ESD2CANxx36-Q1 is an excellent

choice for CAN, CAN-FD, and CAN SiC applications.

The ESD2CANxx36-Q1 is offered in the 3-pin SOT-23

leaded package for easy flow through routing.
