Description and Applications
M/A-COM offers six unique PIN diodes in five
industry standard, low cost, surface mount plastic
packages. These diodes are offered with standard
Sn/Pb plating, as well as with 100% matte Sn plating
on our RoHS compliant equivalent devices. Within
this series, the PIN diodes feature a variety of low
resistance, low capacitance and long minority carrier
lifetime characteristics for microwave control circuit
applications.
The MA4P275 / MA4P7436 has the lowest series
resistance for best performance as Low Loss Series
Switches and High Isolation Shunt Switches. The
MA4P789 / MA4P7433 has the lowest capacitance
and offers the highest Isolation in Series and
Series-Shunt switches through 3 GHz. The
MA4P277 / MA4P7437 and
MA4P278 / MA4P7438 devices have longer intrinsic
layers to provide better distortion performance in
attenuator circuits.
The MA4P282 / MA4P7447 and MA4P274 / MA4P7455
are general-purpose PIN diodes useful in either
switches or attenuators. These parts are available as
Single diodes, Series Tees ( ST ), Series Tee
Reverse ( STR ), Common Cathode pairs ( CK ),
Common Anode pairs ( CA ), and unconnected pairs
in the respective 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 suf-
fix designation is a “T” at the end of the part number.
