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.
