Silicon Diffused Power Transistor
BU4525AL
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic full-pack
envelope intended for use in horizontal deflection circuits of colour television receivers an p.c monitors. Features
exceptional tolerance to base drive and collector current load variations resulting in a very low worst case
dissipation.

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.
