Description
M/A-COM offers six PIN diodes in four industry standard low
cost surface mount plastic packages. Within this series, the PIN
diodes offered feature low resistance, low capacitance and long
minority carrier lifetime.
The MA4P275 has the lowest resistance. The MA4P789 has the
lowest capacitance and offers the highest isolation in series
switches through S-band. The MA4P277 and MA4P278 PINs
have thick intrinsic layers to produce better distortion perfor-
mance in attenuators. The MA4P282 and MA4P274 are general
purpose PIN diodes useful for either switches or attenuators.
These parts are available as single diodes, series pairs, reverse
series pairs (on special order), common cathode pairs, common
anode pairs and unconnected pairs in the appropriate 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) and the SOD-323 (case style 1141) packages. These
packages are supplied on tape and reel for automatic pick and
place assembly on surface mount circuit boards, as indicated by a
“T” to the case style suffix.
