Low Resistance Low Capacitance Plastic Packaged PIN Diodes SMP1320 Series Features ■ Designed for High Performance Wireless 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.

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 Gap figure. Because of the polarity of the diode junction, this low inductance feature is only realizable with the cathode connected to Ground ground. Alpha Industries, Inc.
