8.2.2 Detailed Design Procedure

The ESD2CANFD24 has a VRWM of ±24 V. The bidirectional characteristic enables the signal integrity of the

differential CAN lines to not be impacted by the diode. The low capacitance of 2.5 pF (typical) or less enables

data rates up to 10 Mbps, which allows the designer to meet the requirements for CAN, CANFD, CAN SiC, and

CAN-XL. The 60 Ω split termination improves the electromagnetic emissions behavior of the network by filtering

higher-frequency common-mode noise that may be present on the differential signal lines.
