Power Derating SFE OPERTING RE INFORMTION FORWRD BIS There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. Safe operating area curves indicate I VE 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. The data of Figure is based on T = ; TJ(pk) is variable depending on power level. Second breakdown pulse limits are valid for duty cycles to % but must be derated when T. Second breakdown limitations do not derate the same as thermal limitations. llowable current at the voltages shown on Figure may be found at any case temperature by using the appropriate curve on Figure. TJ(pk) may be calculated from the data in Figure 6. t high case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. REVERSE BIS For inductive loads, high voltage and high current must be sustained simultaneously during turn off, in most cases, with the base to emitter junction reverse biased. Under these conditions the collector voltage must be held to a safe level at or below a specific value of collector current. This can be accomplished by several means such as active clamping, R snubbing, load line shaping, etc. The safe level for these devices is specified as Reverse Bias Safe Operating rea and represents the voltage current condition allowable during reverse biased turnoff. This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode.
