PRODUCTION DATA
Figure 8-7 suggests a protection circuit against 1kV surge (IEC 61000-4-5) transients. Table 8-1 shows the associated bill of materials. SMAJ30CA TVS diodes are rated to operate up to 30V. This makes sure the protection diodes do not conduct if a direct RS-485 bus shorts to 24V DC industrial power rail.
