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 22 suggest a protection circuit against 1 kV surge (IEC 61000-4-5) transients. Table 3 shows the associated Bill of Materials.
