Low Capacitance ESD Protection - SRV05 Series
SRV05 Series 6V 10A Diode Array
RoHS Pb GREEN
Description
The SRV05 integrates low capacitance rail-to-rail diodes with
an additional zener diode to protect each I/O pin against
ESD and high surge events. This robust device can safely
absorb surge current per IEC61000-4-5 (t_P=8/20µs) without
performance degradation and a minimum ±20kV ESD
per IEC61000-4-2. Their very low loading capacitance also
makes them ideal for protecting high speed signal pins.
