TVS Diode Arrays (SPA™Family of Products)
Low Capacitance ESD Protection - SP3011 Series
SP3011 Series 0.40pF Rail Clamp Array for USB 3.0
RoHS Pb GREEN
Description
The SP3011 integrates six channels of ultra-low capacitance
rail-to-rail diodes and an additional zener diode to provide
protection for USB 3.0 ports that may experience
destructive electrostatic discharges (ESD). This high
density array can safely absorb repetitive ESD strikes at the
maximum level specified in the IEC61000-4-2 international
standard (Level 4, ±8kV contact discharge) without
performance degradation. It’s extremely low loading
capacitance makes it ideal for protecting any high-speed
signal pins.
