9.2.2 Detailed Design Procedure
In order to protect bus nodes against high-energy transients, the implementation of external transient protection devices is necessary.
Figure 9-7 Transient protection against ESD, EFT, and Surge transientsFigure 9-7 suggests a protection circuit against 10 kV ESD (IEC 61000-4-2), 4 kV EFT (IEC 61000-4-4), and 1 kV surge (IEC 61000-4-5) transients. Table 9-2 shows the associated Bill of Materials.
