The HSMP-389x series is optimized for switching applications where low resistance at low current and low
capacitance are required. The HSMP-489x series products
feature ultra low parasitic inductance. These products are
specically designed for use at frequencies which are much
higher than the upper limit for conventional PIN diodes.

Typical Applications for HSMP-489x Low Inductance Series
Microstrip Series Connection for HSMP-489x Series
In order to take full advantage of the low inductance of the
HSMP-489x series when using them in series applications,
both lead 1 and lead 2 should be connected together, as
shown in Figure 17.
Figure 16. Internal Connections.
Figure 17. Circuit Layout.
Figure 18. Circuit Layout.
Microstrip Shunt Connections for HSMP-489x Series
In Figure 18, the center conductor of the microstrip line is
interrupted and leads 1 and 2 of the HSMP-489x diode are
placed across the resulting gap. This forces the 1.5 nH lead
inductance of leads 1 and 2 to appear as part of a low pass
lter, reducing the shunt parasitic inductance and increasing the maximum available attenuation. The 0.3 nH of shunt
inductance external to the diode is created by the via holes,
and is a good estimate for 0.032” thick material.
Co-Planar Waveguide Shunt Connection for HSMP-489x Series
Co-Planar waveguide, with ground on the top side of
the printed circuit board, is shown in Figure 20. Since it
eliminates the need for via holes to ground, it oers lower
shunt parasitic inductance and higher maximum attenuation when compared to a microstrip circuit.

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 reow, 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 reow temperatures faster
than those with a greater mass.
Avago Technologies’ diodes have been qualied to the
time-temperature prole shown in Figure 26. This prole
is representative of an IR reow type of surface mount
assembly process.
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 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 reow zone
briey elevates the temperature suciently to produce a
reow 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 reow
zone (T
These parameters are typical for a surface mount assembly process for Avago Technologies 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 reow of solder.
) should not exceed 235°C.
