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 SMBGLCR80 or SMBJLCR80 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 SMCG(J)LCExxx series of low capacitance TVSs that are rated at 100 pF maximum. This results in a
total of 200 pF maximum in this parallel configuration since the SMBG(J)LCR80 is also the same capacitance value of 100 pF.
