Purpose Schottky Diodes
Features
Tight Parameter Distribution
Available as Singles and Pairs
100% DC Tested
Designed for High Volume Commercial
Applications
Available in Tape and Reel Packaging
Description
This series of 8, 20 and 70 V rated low cost plastic packaged
Schottky diodes are designed for general purpose use in RF
applications as detectors, mixers and switches and in digital
pulse forming applications. All diodes are fully characterized
including SPICE model parameters and deliver tight
parameter distribution, minimizing performance variability.
They are available in SC-70, SC-79, SOD-323, SOT-23,
SOT-143 and LGA packages. Wiring configurations include
singles, common cathode, series pairs and unconnected
pairs. Available in tape and reel for pick and place
manufacturing.
