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), 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, and a miniature

SOD-882.

Table 1 describes the various packages and marking of the

SMP1321 series.
