SMP1321 Series

Low Capacitance, Plastic Packaged PIN Diodes

Please note: SMP1321-003LF is being discontinued and is not recommended for new designs. The suggested replacement are SMP1321-079LF and SMP1321-040LF.
SMP1321-007LF is being discontinued and is not recommended for new designs. The suggested replacement is SMP1321-040LF.

SMP1321 Series includes SMP1321-005LF, SMP1321-079LF, SMP1321-040LF and SMP1321-011LF.

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), combined with a low resistance (2.0 Ω maximum at 10 mA), makes the SMP1321 series particularly suited to 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.
