GENERAL DESCRIPTION
Dual, common cathode schottky rectifier diodes in a conventional leaded plastic package and a surface mounting
plastic package. Intended for use as output rectifiers in low voltage, high frequency switched mode power supplies.
The PBYR2045CT series is supplied in the SOT78 conventional leaded package.
The PBYR2045CTB series is supplied in the SOT404 surface mounting package.

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 are given 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
this 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.
