TVS Diode Arrays (SPA^™Family of Products)
Lightning Surge Protection - SP2504N Series
SP2504N Series 2.5V 20A Diode Array
RoHS Pb GREEN
Description
The SP2504N 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 SP2504N
ideal for protecting high-speed signal pins.
