The SZNUP2124 has been designed to protect both CAN and
CAN−FD transceivers from ESD and other harmful transient voltage
events. This device provides two channels of bidirectional protection
in a single, ultra−compact XDFNW3 1x1 mm package. The
combination of low turn−on voltage and low dynamic resistance
XDFNW3
CASE 521AC
(R ) gives the system designer a low cost option for improving
dyn
system reliability by working in conjunction with transceivers
utilizing advanced internal ESD structures.
