These Schottky diodes are specifically designed for both analog and digital applications. This series offers a wide range of specifications and package configurations to give the designer wide flexibility. The HSMS‑281x series of diodes features very low flicker (1/f) noise. Note that Avago’s manufacturing techniques assure that dice found in pairs and quads are taken from adjacent sites on the wafer, assuring the highest degree of match.
The Avago HSMS-281x series are surface‑mount RF Schottky barrier diodes offered in single, dual and quad configurations. They feature low flicker (1/f) noise, low FIT failure rate, and six‑sigma quality, and are available in lead‑free, RoHS‑compliant packages such as SOT‑23, SOT‑323 and SOT‑363.
The document provides electrical ratings, SPICE parameters, mechanical dimensions, recommended PCB footprints, and a detailed reflow profile for reliable SMT assembly. Ordering information and tape dimensions for various package outlines are also included.
