1N6510
Isolated Diode Array with
HiRel MQ, MX, MV, and MSP Screening Options
SCOTTSDALE DIVISION
DESCRIPTION
These low capacitance diode arrays are multiple, discrete, isolated junctions
fabricated by a planar process and mounted in a 16-PIN ceramic flat pack 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 over-voltage 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.
