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 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 rating than the TVS clamping voltage VC.
If using two (2) low capacitance TVS devices in anti-parallel for bidirectional applications, this added protective feature for both directions
(including the reverse of each rectifier diode) is inherently provided in Figure 6. The unidirectional and bidirectional configurations in Figure 5
and 6 will both result in twice the capacitance of Figure 4.
