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, SC-88, SOD-323, SOT-23, SOT-143 and
LGA packages. Wiring configurations include singles, common
cathode, series pairs, unconnected pairs and dual series pairs.
Available in tape and reel for pick and place manufacturing.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
