HSMS-281x
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‑281x series of
diodes features very low flicker (1/f ) noise.
Note that Avago’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.

Applications Information
Introduction — Product Selection
Avago’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‑282x fam‑
ily use the same diode chip, and the same is true of the
HSMS-281x and HSMS-280x families. Each family has a dif‑
ferent 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 applications 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 volt‑
age applications and the HSMS-281x family for low flicker
noise applications.

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 pack‑
age placement by automated assembly equipment with‑
out adding parasitics that could impair the performance.
