10.2.2 Detailed Design Procedure
To protect bus nodes against high-energy transients, the implementation of external transient protection devices is therefore necessary. Figure 10-4 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.
