SMP1321-007
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.
