DESCRIPTION
Planar Schottky barrier diode with an
integrated protection ring against
static discharges. This surface
mounted diode is encapsulated in a
hermetically sealed SOD80C glass
SMD package with tin-plated metal
discs at each end. It is suitable for
“automatic placement” and as such it
can withstand immersion soldering.

Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
