3 Description
ESD752 is a bidirectional ESD protection diode for
Controller Area Network (CAN) interface protection.
ESD752 is rated to dissipate contact ESD strikes
specified in the IEC 61000-4-2 standard. The low
dynamic resistance and low clamping voltage enables
system level protection against transient events. This
protection is key as industrial 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 3pF (typical) line capacitance of
ESD752 is suitable for CAN, CANFD, CAN SiC, and
CAN-XL applications that can support data rates up to
20Mbps.
