SCHEMATIC APPLICATIONS

The TVS low capacitance device configuration is shown in Figure 4. As a further option for unidirectional applications, an additional low

capacitance rectifier diode may be used in parallel in the same polarity direction as the TVS as shown in in Figure 5. In applications where

random high voltage transients occur, this will prevent reverse transients from damaging the internal low capacitance rectifier diode and also

provide a low voltage conducting direction. The added rectifier diode should be of similar low capacitance and also have a higher reverse voltage

in anti-parallel for bidirectional applications, this added protective feature for both directions (including the reverse of each rectifier diode) is also

provided. The unidirectional and bidirectional configurations in Figure 5 and 6 will both result in twice the capacitance of Figure 4.
