Description/Applications
These Schottky diodes are
specifically designed for both
analog and digital applications.
This series offers a wide range of
specifications and package
configurations to give the
designer wide flexibility. The
HSMS-281x series of diodes
features very low flicker (1/f)
noise.
Note that Agilent’s manufacturing
techniques assure that dice found
in pairs and quads are taken from
adjacent sites on the wafer,
assuring the highest degree of
match.
