There are two limitations on the power handling ability of

a transistor: average junction temperature and second

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.

limits are valid for duty cycles to 10% provided

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.
