Isolated Diode Array with
HiRel MQ, MX, MV, and MSP Screening Options
SCOTTSDALE DIVISION
DESCRIPTION APPEARANCE
These low capacitance diode arrays are multiple, discrete, isolated junctions fabricated
by a planar process and mounted in a 10-PIN package for use as steering diodes
protecting up to eight I/O ports from ESD, EFT, or surge by directing them to the positive
side of the power supply line and 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
10-PIN Ceramic
packaging and improved reliability. This is a result of fewer pick and place operations,
Flat Pack
smaller footprint, smaller weight, and elimination of various discrete packages that may
not be as user friendly in PC board mounting.
