Schematic diagram
The GESDBW2V8Q8 has a low typical capacitance of 0.65pF and operates with virtually
no insertion loss to 1GHz. The GESDBW2V8Q8 is in an SOP-8 package and may be used to
protect two high-speed line pairs. This makes the device ideal for protection of data lines such
as 10/100M Ethernet, gigabit Ethernet interfaces. It may be used to meet the ESD immunity
requirements of IEC61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).
It has been specifically designed to protect sensitive components which are connected
to high-speed data and transmission lines from overvoltage caused by ESD(electrostatic
discharge), CDE (Cable Discharge Events),and lightning.
