SMP1320-007
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
ground.
