SP3012 Datasheet, PDF (1/4 Pages) Littelfuse – SP3012 Series 0.5pF Rail Clamp Array

TVS Diode Arrays (SPA^™Family of Products)
Low Capacitance ESD Protection - SP3012 Series
SP3012 Series 0.5pF Rail Clamp Array
RoHS Pb GREEN
Description
The SP3012 integrates 4 channels of ultra low capacitance
rail-to-rail diodes and an additional zener diode to provide
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). This robust
device can safely absorb repetitive ESD strikes above the
maximum level specified in the IEC61000-4-2 international
standard (±8kV contact discharge) without performance
degradation. The extremely low loading capacitance also
makes it ideal for protecting high speed signal pins such as
HDMI, USB3.0, USB2.0, and IEEE 1394.
