LOW CAPACITANCE RECTIFIER
S C O T T S D A L E D I V I S I O N
DESCRIPTION
APPEARANCE
The ELCR80 low capacitance rectifier is used in parallel with a low-capacitance
transient voltage suppressor (TVS) such as the LCE6.5-170A series for
unidirectional applications as shown in Figure 4. It is rated for 100 Amp
forward surges to compliment this 1500 Watt TVS series and also provide a
low capacitance and a low forward (VF) voltage with fast response time. The
low capacitance rating of 100 pF when used in parallel to the LCE6.5-170A
series will result in a total capacitance of 200 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
T-18
and IEC61000-4-4 respectively.
