This series is not recommended for new designs. Suggests to use SP1021-01WTG for the new designs in near future. The SP1014 includes back-to-back Zener diodes that provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). It measures 0.52 x 0.27mm making it a true 0201 footprint or about 30% smaller than existing 0201 ESD footprints. The SP1014 can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation, and the back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present.
