Agilent HSMS-280x
Surface Mount RF
Schottky Barrier Diodes
Data Sheet
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-280x series of diodes is
optimized for high voltage
applications.

Applications Information
Introduction —
Product Selection
Agilent’s family of Schottky
products provides unique solu-
tions to many design problems.
The first step in choosing the right
product is to select the diode type.
All of the products in the
HSMS-280x family use the same
diode chip, and the same is true of
the HSMS-281x and HSMS-282x
families. Each family has a
different set of characteristics
which can be compared most
easily by consulting the SPICE
parameters in Table 1.
A review of these data shows that
the HSMS-280x family has the
highest breakdown voltage, but at
the expense of a high value of
series resistance (Rs). In applica-
tions which do not require high
voltage the HSMS-282x family,
with a lower value of series
resistance, will offer higher
current carrying capacity and
better performance. The HSMS-
281x family is a hybrid Schottky
(as is the HSMS-280x), offering
lower 1/f or flicker noise than the
HSMS-282x family.
In general, the HSMS-282x family
should be the designer’s first
choice, with the -280x family
reserved for high voltage applica-
tions and the HSMS-281x family
for low flicker noise applications.
Assembly Instructions
SOT-323 PCB Footprint
A recommended PCB pad layout
for the miniature SOT-323 (SC-70)
package is shown in Figure 6
(dimensions are in inches). This
layout provides ample allowance
for package placement by auto-
mated assembly equipment
without adding parasitics that
could impair the performance.

SOT-363 PCB Footprint
A recommended PCB pad layout
for the miniature SOT-363 (SC-70,
6 lead) package is shown in
Figure 7 (dimensions are in
inches). This layout provides
ample allowance for package
placement by automated assembly
equipment without adding
parasitics that could impair the
performance.
