operation; i.e., the transistor must not be subjected to greater
dissipation than the curves indicate.
The data of Figure 5 is based on T

C
is
variable depending on conditions. Second breakdown pulse
limits are valid for duty cycles to 10% provided T
J(pk)
≤ 150°C. At high case temperatures, thermal limitations will
reduce the power that can be handled to values less than the
limitations imposed by second breakdown.
