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.
