Description

The SMP1352 series of plastic packaged, surface
mountable, low capacitance (0.3 pF) silicon PIN diodes
are designed for large signal switch applications from
10 MHz to beyond 2 GHz.These diodes have a reverse
voltage rating of 200 V and are designed for use in low
distortion switches that are required to hold off large RF
voltages.The nominal 50 µm I region width, combined with
the typical 1.5 µS carrier lifetime, results in a PIN diode
with low forward resistance and low distortion
characteristics.
