8.2.2 Detailed Design Procedure
To protect bus nodes against high-energy transients, the implementation of external transient protection devices is necessary.
Figure 8-5 Transient Protection Against ESD, EFT, and Surge TransientsFigure 8-5 shows 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 8-1 lists the associated Bill of Materials.
