LOW CAPACITANCE RECTIFIER

DESCRIPTION
APPEARANCE
The LCR60 low capacitance rectifier is used in parallel applications with a low-
capacitance transient voltage suppressor (TVS) such as the SAC5.0-50 series
for unidirectional applications as shown in Figure 4. It is rated for 44 Amp
forward surges to compliment this 500 Watt TVS series and also provide a
low capacitance and a low forward (VF) voltage with fast response time. The
low capacitance rating of 30 pF when used in parallel to the SAC series will
result in a total capacitance of 60 pF or less at zero volts for protecting higher
frequency applications from inductive switching threats or electrical systems
involving secondary lightning effects per IEC61000-4-5 as well as RTCA/DO-
160D or ARINC 429 for airborne avionics. With their fast response time, they
also provide ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4
DO-41
respectively.

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.
