General Purpose ESD Protection - SP1004 Series
Description
Applications
Back-to-back 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 at 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 protecting high-
speed signal pins.

• ESD, IEC61000-4-2, ±8kV
contact, ±15kV air
• Capable of withstanding
>1,000 ±8kV ESD strikes
