SP3021 Series

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.
