Schematic Applications
The TVS low capacitance device configuration is shown in Fig.4. As a further option for unidirectional applications, an
additional low capacitance rectifier diode may be used in parallel in the sane polarity direction as the TVS as shown in
Fig.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 also provided. The unidirectional and bidirectional
configurations in Fig.5 and 6 will both in twice the capacitance of Fig.4
