HSMS-281x
Surface Mount RF Schottky Barrier Diodes
Data Sheet
Description/Applications
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.
Features
• Surface Mount Packages
• Low Flicker Noise
• Low FIT (Failure in Time) Rate*
• Six-sigma Quality Level
• Single, Dual and Quad Versions
• Tape and Reel Options Available
• Lead-free
• For more information see the Surface Mount Schottky

Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to the device.
2. TC = +25°C, where TC is defined to be the temperature at the package pins where contact is made to the circuit board.
ESD WARNING: Handling Precautions Should Be Taken To Avoid Static Discharge.
