3 Description
The ESD2CANxx24-Q1 is a bidirectional ESD
protection diode for Controller Area Network (CAN)
interface protection. The ESD2CANxx24-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 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 3 pF (typical) or less line
capacitance of the ESD2CANxx24-Q1 is suitable for
CAN, CANFD, CAN SiC, and CAN-XL applications
that can support data rates up to 10 Mbps.
The ESD2CANxx24-Q1 is offered in two leaded
packages for easy flow through routing.
