Description/Applications
The HSMP-381x series is
specifically designed for low
distortion attenuator applica-
tions. The HSMP-481x products
feature ultra low parasitic
inductance in the SOT-23 and
SOT-323 packages. They are
specifically designed for use at
frequencies which are much
higher than the upper limit for
conventional diodes.

A SPICE model is not available
for PIN diodes as SPICE does not
provide for a key PIN diode
characteristic, carrier lifetime.

Typical Applications for HSMP-481x Low Inductance Series
Microstrip Series
Connection for
HSMP-481x Series
In order to take full advantage of
the low inductance of the
HSMP-481x series when using
them in series applications,
both lead 1 and lead 2 should be
connected together, as shown in
Figure 7.

Microstrip Shunt
Connections for
HSMP-481x Series
In Figure 8, the center
conductor of the microstrip
line is interrupted and
leads 1 and 2 of the
HSMP-481x series 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
filter, reducing the shunt
parasitic inductance and
increasing the maximum
available attenuation. The
0.3 nHof shunt inductance
external to the diode is created
by the via holes, and is a good
estimate for 0.032" thick material.
