SCHEMATIC APPLICATIONS
A typical low capacitance TVS device configuration is shown in Figure 4 when used with a separate rectifier to maintain low capacitance. As
shown, an additional low capacitance rectifier diode is used in parallel in the same polarity direction as the TVS. In applications where random
high voltage transients occur, this will prevent reverse transients from damaging the internal low capacitance rectifier diode within the TVS and
also provide a low voltage conducting direction. This added rectifier diode such as the LCR60 is of similar low capacitance as the TVS and also
has a higher reverse voltage rating than the TVS clamping voltage VC. The unidirectional configuration in Figure 4 will result in twice the
capacitance of the SACxxx series of low capacitance TVSs that are rated at 30 pF maximum. This results in a total of 60 pF maximum in this
parallel configuration since the LCR60 is also the same capacitance value of 30 pF.
