TVS Diode Arrays (SPA ? Family of Products)
Lightning Surge Protection - SP4062 Series
SP4062 Series 3.3V 20A Diode Array
RoHS
Pb GREEN
Description
The SP4062 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 SP4062
ideal for protecting high-speed signal pins.
