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.
