MAIN APPLICATIONS
Where ESD protection for high speed datalines is
required :
LAN / WAN equipment
Computer I/O
Graphic video port
Set top box I/O
DESCRIPTION
ARRAY of 12 diodes configured by cells of 2
diodes, each cell being used to protect signal line
from transient overvoltages by clamping action.
Its very low capacitance allows to protect fast
signals with no distortion. It is particularlysuited for
the protection of graphic video ports.
