Switch Applications
■ 0.9 Ω Resistance, 0.3 pF Capacitance
■ Multiple Package Configurations
■ Available in Tape and Reel Packaging
Description
The SMP1320 series of plastic packaged, surface
mountable PIN diodes are designed for high volume switch
applications from 10 MHz to beyond 2 GHz. The low
current performance of these diodes (0.9 Ω maximum at
10 mA and 2 Ω typical at 1 mA) make the SMP1320 series
particularly suited to 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 (SMP1320-007), the small footprint SC-79 and the
miniature SC-70.
