HSMP-389Z Low Current Series PIN Switch in a Compact SOD-323 Package - App Note

From Avago Technologies
 

 
PIN diodes are particularly useful as the switching element in SPST and SPNT configurations. The HSMP-389Z is one of the two switching diodes available in the ultra-miniature SOD-323 package. The HSMP-389Z is an Epitaxial (Epi) PIN junction diode and is best suited to low current series switching application. If either low capacitance at zero bias or high linearity is the primary consideration, then the thin bulk PIN diode HSMP-386Z should be chosen. The HSMP-389Z PIN diode is suitable for implementing broadband series switches. It can also be configured as a narrow-band series switch with improved isolation over the broadband version. The tiny footprint makes it eminently suitable for complex switching networks requiring a large number of PINs such as those encountered in CATV/SATV distribution systems.
Products & Services
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).

Diode arrays are composed of multiple discrete (usually unconnected) diodes on a single silicon chip. Diode arrays are important semiconductor products because they save assembly time and improve reliability over individually packaged diodes. In general, diode arrays use four or more diodes in a single package. Search by Specification | Learn more about Diode Arrays
RF diodes are designed to handle high-power radio frequency (RF) signals in stereo amplifiers, radio transmitters, television monitors, and other RF or microwave devices. Search by Specification | Learn more about RF Diodes
Power diodes are used mainly in high-power applications. They are built with large P-N junctions in order to pass large amounts of current and dissipate large amounts of heat. Search by Specification | Learn more about Power Diodes
