There are two limitations on the power handling ability of

limits of the transistor that must be observed for reliable

operation; i.e., the transistor must not be subjected to greater

Figure 5. At high case temperatures, thermal limitations will

reduce the power that can be handled to values less than the

limitations imposed by second breakdown.
