DATA SHEET SMP1321 Series: Low Capacitance, Plastic Packaged PIN Diodes Applications High-performance wireless switches Features Capacitance: 0.18 pF typical 30 V Series resistance: 1.05 typical 10 mA Packages rated MSL1, 260 C per JEDEC J-STD-020 Description The SMP1321 series of plastic packaged, surface mountable PIN diodes is designed for use in high volume switch applications from 10 MHz to more than 10 GHz. The low capacitance of these diodes (0.25 pF maximum at 30 V), combined with a low resistance (2.0 maximum at 10 mA), makes the SMP1321 series particularly suited for high isolation, series-connected PIN diode switches in battery operated circuits. The SMP1321 series is available in a selection of plastic packages and a variety of configurations that include a small footprint SC-79, a low inductance SOT-23, a miniature SOD-882, and an SOD-323. Table 1 describes the various packages and marking of the SMP1321 series. Skyworks Solutions, Inc.
