Description/Applications
The HSMP-382x series is optimized for switch ing ap-
plications where ultra-low resistance is required. The
HSMP-482x diode is ideal for limiting and low induc-
tance switching applications up to 1.5 GHz.
A SPICE model is not available for PIN diodes as SPICE
does not provide for a key PIN diode characteristic, carrier
lifetime.

Microstrip Series Connection for HSMP-482x Series
In order to take full advantage of the low inductance
of the HSMP-482x series when using them in series
applications, both lead 1 and lead 2 should be connected
together, as shown in Figure 14.
Figure 16. Equivalent Circuit.
Co-Planar Waveguide Shunt Connection for HSMP-482x Series
Co-Planar waveguide, with ground on the top side of
the printed circuit board, is shown in Figure 17. Since
it eliminates the need for via holes to ground, it o ers
lower shunt parasitic inductance and higher maximum
attenuation when compared to a microstrip circuit. See
AN1050 for details.

Microstrip Shunt Connections for HSMP-482x Series
In Figure 15, the center conductor of the microstrip line
is interrupted and leads 1 and 2 of the HSMP-482x diode
are placed across the resulting gap. This forces the 0.5
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.

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 re ow, 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-323/-23 package, will reach solder re ow
temperatures faster than those with a greater mass.
Avagos diodes have been quali ed to the time-
temperature pro le shown in Figure 21. This pro le is
representative of an IR re ow 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
re ow zone brie y elevates the temperature su ciently
to produce a re ow 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
re ow zone (TMAX) should not exceed 260°C.
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 re ow of solder.
