SMP1320-007
In the -007 configuration of the SOT-23 package, the package induc-
tance 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
realizable only with the cathode
connected to ground.
