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.
