Pulse Test: Pulse Width v 300 ms, Duty Cycle v 2.0%. 20 There are two limitations on the power handling ability of 50 ms a transistor: average junction temperature and second 10 dc 1 ms breakdown. Safe operating area curves indicate IC − VCE (AMP) 6 limits of the transistor that must be observed for reliable 4 operation; i.e., the transistor must not be subjected to greater dissipation than the curves indicate. CURRENT 500 ms 2 250 ms The data of Figure 2 is based on T OR C = 25°C; TJ(pk) is variable depending on power level.
