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

=8/20s) 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.
