TYPICAL THERMAL RESPONSE

There are two limitations on the power handling ability of a transistor: average junction temperature and second

operation; i.e., the transistor must not be subjected to greater dissipation than the curves indicate.

debate the same as thermal limitations. Allowable current at the voltages shown on Fig. 7 may be found at any case

temperature by using the appropriate curve on Fig. 9.

At high case temperatures, thermal limitations will reduce the power that can be handled to values less than the

limitations imposed by second breakdown.

Use of reverse biased safe operating area data (Fig. 8) is discussed in the applications information section.
