DESCRIPTION
APPLICATIONS
NPN overlay transistors in TO-39 metal packages with the
collector connected to the case. The devices are primarily
intended for class-A, B or C amplifiers, frequency multiplier
and oscillator circuits.
• The transistors are intended for use in output, driver or
pre-driver stages in VHF and UHF equipment.

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.
