Schottky barrier diodes BAT81; BAT82; BAT83
FEATURES
• Low forward voltage
• High breakdown voltage
• Guard ring protected
DESCRIPTION
Planar Schottky barrier diode with an integrated protection ring against static
discharges, encapsulated in a hermetically-sealed subminiature SOD68
(DO-34) package. The diode is suitable for mounting on a 2 E (5.08 mm) pitch.
• Hermetically-sealed leaded glass
package
• Low diode capacitance.

DEFINITIONS
Data sheet status
Objective specification This data sheet contains target or goal specifications for product development.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later.
Product specification This data sheet contains final product specifications.
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
