Figure 6. Single Wire CAN Network
Figure is the recommended solution for transient EMI/ESD protection. This circuit is shown in the
Society of Automotive Engineers February, 2000 J2411 “Single Wire CAN Network for Vehicle Applications” specification
(Figure 6, page 11). Note: the dual common anode zener configuration shown above is electrically equivalent to a dual common
cathode zener configuration.
