Low Capacitance ESD Protection - SP3021 Series
Description
Features
Applications
The SP3021 includes back-to-back TVS diodes fabricated
in a proprietary silicon avalanche technology to provide
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). These robust
diodes can safely absorb repetitive ESD strikes up to the
maximum level specified in the IEC61000-4-2 international
standard without performance degradation. The back-to-
back configuration provides symmetrical ESD protection for
data lines when AC signals are present.
