MACOM offers silicon PIN diodes in five standard, low cost, surface mount plastic packages for use as switches and attenuators. The diodes are offered with standard Sn/Pb plating, as well as with 100% matte Sn plating on our RoHS compliant devices. These PIN diodes feature a variety of I-region lengths resulting in lower resistance, and lower capacitance devices for various microwave control circuit applications.
The MA4P277 / MA4P7437 / MADP-007437 series and MA4P278 / MA4P7438 / MADP-007438 devices have thicker intrinsic regions to provide lower distortion in attenuator circuits.
The diodes come in a variety of chip configurations and 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.
MACOM’s PIN diodes are available in the SOT-23 (case style 287), the SOT-143 (case style 1068), the SOT-323/SC-70 (3L) (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. The tape and reel suffix designation is a “T” at the end of the part number.
