GENERAL DESCRIPTION
AVX offers ultra-low capacitance ESD protection in the Sub
1pF range for use in circuits that are sensitive to capacitance.
The Sub pF Varistor (SPV) is available in 0.8pF and 0.4pF
capacitance values in a compact 0402 low profile package.
SPV devices provide excellent response time to ESD strikes
to protect sensitive circuits from over voltage conditions.
The development of new information processing technologies
call for ever increasing digital system speeds. Higher speeds
necessitate the use of ultra-low capacitance values in order to
minimize signal distortion.
