The SMP1302 series of plastic packaged, surface mountable, low
capacitance (0.3 pF) silicon PIN diodes is designed for highvolume
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, makes these diodes
useful in large signal switch applications.
The SMP1302 series provides single and dual diodes in a
selection of plastic packages including SOT-23, SOD-323, small
footprint SC-79, an ultralow inductance (0.2 nH) SOT-143
(SMP1302-017), and miniature SC-70.
A four-diode array is available in an SOT-5 package (SMP1302-
027) designed for insertion in the commonly used four-diode PI
attenuator circuits.
SMP1302 Series includes SMP1302-003LF, SMP1302-011LF, SMP1302-040LF, SMP1302-078LF, and SMP1302-079LF.
