Switching Diode Array

Steering Diode TVS Array

TM

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.
