SP4061 Datasheet, PDF (1/4 Pages) Littelfuse – SP4061 Series 2.5V 20A Rail Clamp Array

TVS Diode Arrays (SPA^™Family of Products)
Lightning Surge Protection - SP4061 Series
SP4061 Series 2.5V 20A Rail Clamp Array
RoHS Pb GREEN
Description
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.
