Safe operating area curves indicate IC – VCE operation i.e., the transistor must not be subjected to greater dissipation than the curves indicate. The data of Figure 5 is based on TJ(pk) = 150C; TC is variable depending on conditions. Second breakdown pulse limits are valid for duty cycles to 10% provided TJ(pk) 150C. At high case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. 100 µs 1.0 ms dc SECOND BREAKDOWN LIMITED BONDING WIRE LIMITED THERMALLY LIMITED @ TC = 25°C PULSE CURVES APPLY BELOW RATED VCEO 2.0 3.0 5.0 7.0 10 20 30 50 VCE, COLLECTOR-EMITTER VOLTAGE (VOLTS) 70 100 Figure 5.
