6507A Isolated Diode Array with HiRel MQ, MX, MV, and SP Screening Options SCOTTSDALE DIVISION APPEARANCE These low capacitance diode arrays with common anode 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 ground (see figure 1). This circuit application is further complimented by the 1N6506 (separate data sheet) that has a common cathode. 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. 14-PIN Ceramic DIP WWW .
