10 There are two limitations on the power handling ability of 7.0 a transistor: average junction temperature and second 5.0 100 ms 5.0 ms 1.0 ms breakdown. Safe operating area curves indicate IC − VCE (AMP) 3.0 operation i.e., the transistor must not be subjected to greater 2.0 T dissipation than the curves indicate. J = 150°C dc The data of Figure 5 is based on TJ(pk) = 150_C; TC 1.0 is variable depending on conditions. Second breakdown OR CURRENT 0.7 SECOND BREAKDOWN pulse limits are valid for duty cycles to 10% provided 0.5 LIMITED TJ(pk) ≤ 150_C.
