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.
SC-79
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.
