APPLICATION SCHEMATICS

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. The Microsemi recommended rectifier part number for the application in

figure 5 is the “SMBJLCR80” or “SMBGLCR80” depending on the terminal configuration desired. 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.
