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. Typical
applications of these Schottky
diodes are mixing, detecting,
switching, sampling, clamping,
and wave shaping. The
HSMS-2800 series of diodes is
optimized for high voltage
applications. The HSMS-2810
series of diodes features very low
flicker (1/f) noise. The

HSMS-2820 series of diodes is the
best all-around choice for most
applications, featuring low series
resistance, low forward voltage at
all current levels and good RF
characteristics. The HSMS-2860
series is a high performance
diode offering superior Vf and
ultra-low capacitance.
Note that HP’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.

Quad Capacitance
Capacitance of Schottky diode
quads is measured using an
HP4271 LCR meter. This
instrument effectively isolates
individual diode branches from
the others, allowing accurate
capacitance measurement of each
branch or each diode. The
conditions are: 20 mV R.M.S.
voltage at 1 MHz. HP defines this
measurement as “CM”, and it is
equivalent to the capacitance of
the diode by itself. The equivalent
diagonal and adjacent
capacitances can then be
calculated by the formulas given
below.
In a quad, the diagonal capaci-
tance is the capacitance between
points A and B as shown in the
figure below. The diagonal
capacitance is calculated using
the following formula
C1 x C2 C3 x C4
CDIAGONAL = _______ + _______

The equivalent adjacent

calculated using the following
