Product specification
BU2708AF
GENERAL DESCRIPTION
High voltage, high speed switching npn transistor in a plastic full-pack envelope. Intended for use in horizontal
deflection circuits of colour television receivers. Features exceptional tolerance to base drive and collector current
load variations, resulting in a low worst-case dissipation. Designed to withstand VCES pulses up to 1700 V.

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.
