Lightning Surge Protection - SP4061 Series
SP4061 Series
SP4061
161
Description
Applications
The SP4061 integrates 4 channels of low capacitance
diodes with an additional zener diode to protect sensitive
I/O pins against lightning induced surge events and
ESD. This robust device can safely absorb up to 20A per
IEC61000-4-5 (t
P
=8/20μs) without performance degradation
and a minimum ±30kV ESD per IEC61000-4-2 international
standard. The low loading capacitance makes the SP4061
ideal for protecting high-speed signal pins.
