Steering Diode TVS ArrayTM
SCOTTSDALE DIVISION
DESCRIPTION
These low capacitance diode arrays are multiple, discrete, isolated junctions
fabricated by a planar process and mounted in a 14-PIN package for use as
steering diodes protecting up to ten I/O ports from ESD, EFT, or surge by
directing them either to the positive side of the power supply line or to
ground (see figure 1). An external TVS diode may be added between the
positive supply line and ground to prevent overvoltage on the supply rail.
They may also be used in fast switching core-driver applications. This
includes computers and peripheral equipment such as magnetic cores, thin-
film memories, plated-wire memories, etc., as well as decoding or encoding
applications. These arrays offer many advantages of integrated circuits such
as high-density packaging and improved reliability. This is a result of fewer
pick and place operations, smaller footprint, smaller weight, and elimination
of various discrete packages that may not be as user friendly in PC board
mounting.
