TVS Diode Arrays (SPA^™Family of Products)
Low Capacitance ESD Protection - SP3031 Series
SP3031 Series 0.8pF 10kV Unidirectional Discrete TVS
RoHS Pb GREEN
Description
The SP3031 includes low capacitance rail to rail diodes
with an additional Zener diode to provide 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 IEC61000-4-2 international standard
without performance degradation. The low loading
capacitance makes it ideal for protecting high speed data
lines.
