SMP1321-007
For the -007 configuration of the SOT-23 package, the package
inductance is effectively reduced to 0.4 nH compared to the
1.5 nH value of the standard configuration. This lower inductance
is particularly beneficial when the diodes are used as shunt
connected switches at frequencies higher than 500 MHz in which
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 Figure 1. Because of the polarity of the diode junction,
this low inductance feature is realizable only with the cathode
connected to ground.

Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMP1321 series is rated to Moisture Sensitivity Level 1
(MSL1) at 260 °C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
