General Purpose ESD Protection - SP1011 Series
Description
Applications
Zener diodes fabricated in a proprietary silicon avalanche
technology protect each I/O pin to provide a high level of
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). These robust
diodes can safely absorb repetitive ESD strikes above
the maximum level specified in the IEC 61000-4-2
international standard (Level 4, ±8kV contact discharge)
without performance degradation. Their very low loading
capacitance also makes them ideal for protection high-
speed signal pins.
Features
• ESD, IEC61000-4-2,
