3 Description
The ESD2CANFD24 is a bidirectional ESD protection
diode for Controller Area Network (CAN) interface
protection. The ESD2CANFD24 is rated to dissipate
contact ESD strikes beyond the maximum level
specified in the IEC 61000-4-2 standard (±25-kV
Contact, ±25-kV Airgap). The low dynamic resistance
and low clamping voltage enables system level
protection against transient events. This protection is
key as 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 CAN bus lines (CANH
and CANL) from the damage caused by ElectroStatic
Discharge (ESD) and other transients. Additionally,
the 2.5 pF (typical) or less line capacitance of the
ESD2CANFD24 is suitable for CAN, CANFD, CAN
SiC, and CAN-XL applications that can support data
rates up to 10 Mbps.
The ESD2CANFD24 is offered in a leaded package
for easy flow through routing.
