Description
M/A-COM offers six unique PIN diodes in five industry
standard, low cost, surface mount plastic packages. Within
this series, the PIN diodes offered, feature a variety of low
resistance, low capacitance and long minority carrier
lifetime characteristics.
The MA4P275 has the lowest series resistance for Series
Insertion Loss and Shunt Isolation switches. The MA4P789
has the lowest capacitance and offers the highest isolation
in Series and Series-Shunt switches through 3 GHz. The
MA4P277 and MA4P278 PIN diodes have longer intrinsic
layers to produce better distortion performance in
attenuators. The MA4P282 and MA4P274 are general-
purpose PIN diodes useful in either switches or attenuators.
These parts are available as single diodes, series pairs
( ST ) , reverse series pairs ( STR ) , common cathode pairs
( CK ) , common anode pairs ( CA ) , and unconnected pairs
in the featured packages.
The SMPP series of PIN diodes is available in the SOT-23
(case style 287), the SOT-143 (case style 1068), the SOT-
323 (case style 1146) , the SOD-323 (case style 1141) , and
the SC-79 (case style 1279) packages. These packages are
supplied on tape and reel for automatic pick and place
assembly on surface mount circuit boards. The tape and reel
suffix designation is a “T” at the end of the part number.
