designed for use in general?purpose amplifier and switching
circuits. Recommended for use in 5 to 20 Watt audio amplifiers
utilizing complementary symmetry circuitry.

There are two limitations on the power handling ability of
a transistor: average junction temperature and second
breakdown. Safe operating area curves indicate IC ? VCE
limits of the transistor that must be observed for reliable
operation; i.e., the transistor must not be subjected to greater
dissipation than the curves indicate.
The data of Figure 1 is based on TJ(pk) = 150C; TC is
variable depending on conditions. Second breakdown pulse
limits are valid for duty cycles to 10% provided TJ(pk)
150C. At high case temperatures, thermal limitations
will reduce the power that can be handled to values less then
the limitations imposed by second breakdown.
