Safe operating area curves indicate Ic Veg limits of the transistor that must be observed for reliable operation, 1e , the transistor must not be subjected to greater dissipation than the curves indicate. wy The data of Figure 1 is based on Ty(py) = 150C: Te 1s variable depending on conditions. Second breakdown pulse hmits are valid for duty cycles to 10% provided Tyipx) S150C. At high case temperatures, thermal Inmitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. {See AN-415} 3-317 &
