Low Capacitance
Plastic Packaged PIN Diodes
SMP1321 Series
Features
■ Designed for High Performance Wireless
Switch Applications
■ 0.25 pF Capacitance Specified
■ Multiple Package Configurations
■ Available in Tape and Reel Packaging
Description
The SMP1321 series of plastic packaged, surface
mountable PIN diodes are designed for high volume switch
applications from 10 MHz to beyond 2 GHz. The low
capacitance of these diodes (0.25 pF) combined with its low
resistance (2.0 Ω maximum at 10 mA) make the SMP1321
series particularly suited to high isolation series connected
PIN diode switches in battery operated circuits. Available
in a selection of plastic packages and in a variety of
configurations including a low inductance (0.4 nH) SOT-23
(SMP1321-007), the small footprint SC-79 and the
miniature SC-70.

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
