Description

The SMP1302 series of plastic packaged, surface

mountable, low capacitance (0.3 pF) silicon PIN diodes

are designed for high volume switch and attenuator

applications from 10 MHz to beyond 2 GHz. These diodes

are designed for use in low distortion PI and TEE

attenuators with low drive current (maximum resistance

at 1 mA is 10

Ω) commonly used in TV distribution and

cellular base station applications. The nominal 50

µm

I region width combined with a maximum resistance of

3

Ω at 10 mA, make these diodes useful in large signal

switch applications. Available as single and dual diodes

in a selection of plastic packages including SOT-23,

SOD-323,

small

footprint

SC-79

and

miniature

SC-70. Available in a SOT-5 (SMP1302-027) package as

a four diode array designed for insertion in the commonly

used 4 diode PI attenuator circuit.
