SMP1322-007
In the -007 configuration of the SOT-23 package, the package
inductance is effectively reduced to 0.4 nH, in comparison to
the 1.5 nH value of the standard configuration. This lower
inductance will be particularly beneficial when the diodes are
used as shunt connected switches at frequencies higher than
500 MHz, where inductance is the primary limitation on
maximum switch isolation.
To achieve the effective 0.4 nH, the SOT-23 package
must be inserted in the microstrip circuit board with a
gap in the trace, as shown
in the figure. Because
of the polarity of the
diode junction, this low
inductance feature is only
realizable with the cathode
connected to ground.
