MMAD1108(e3)
Switching Diode Array
Steering Diode TVS ArrayTM
Available
DESCRIPTION
These low capacitance diode arrays are multiple, discrete, isolated junctions fabricated by a
planar process and mounted in a 16-Pin SOIC package for use as steering diodes protecting
up to eight 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. They are available
with either tin-lead plating terminations or as RoHS compliant with annealed matte-tin finish.
