a transistor: average junction temperature and second
breakdown. Safe operating area curves indicate I
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.
is variable depending on conditions. Second breakdown
pulse limits are valid for duty cycles to 10% provided
T
Figure 4. At high case temperatures, thermal limitations will
reduce the power that can be handled to values less than the
limitations imposed by second breakdown.
