Quad Capacitance
A
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. Avago 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 capacitance 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 = _______
C1 + C2

The equivalent adjacent capacitance is the capacitance

Applications Information Introduction —
Product Selection
0.026
Avago’s family of Schottky products provides unique
solutions 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 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 voltage
applications and the HSMS-281x family for low flicker
noise applications.

SMT Assembly
Reliable assembly of surface mount components is a
complex process that involves many material, process, and
equipment factors, including: method of heating (e.g., IR
or vapor phase reflow, wave soldering, etc.) circuit board
material, conductor thickness and pattern, type of solder
alloy, and the thermal conductivity and thermal mass of
components. Components with a low mass, such as the
SOT package, will reach solder reflow temperatures faster
than those with a greater mass.
zones. The preheat zones increase the temperature of the
board and components to prevent thermal shock and
begin evaporating solvents from the solder paste. The
reflow zone briefly elevates the temperature sufficiently
to produce a reflow of the solder.
The rates of change of temperature for the ramp-up and
cool-down zones are chosen to be low enough to not
cause deformation of the board or damage to components due to thermal shock. The maximum temperature
in the reflow zone (TMAX) should not exceed 260°C.
Avago’s SOT diodes have been qualified to the timetemperature profile shown in Figure 8. This profile is
representative of an IR reflow type of surface mount assembly process.
These parameters are typical for a surface mount assembly process for Avago diodes. As a general guideline, the
circuit board and components should be exposed only
to the minimum temperatures and times necessary to
achieve a uniform reflow of solder.
After ramping up from room temperature, the circuit
board with components attached to it (held in place
with solder paste) passes through one or more preheat
