20 There are two limitations on the power handling ability of 10 100 ms a transistor: average junction temperature and second breakdown. Safe operating area curves indicate I 5.0 500 ms C − VCE (AMP) limits of the transistor that must be observed for reliable dc 2.0 T operation, i.e., the transistor must not be subjected to greater J = 150°C 1.0 BONDING WIRE LIMITED dissipation than the curves indicate. THERMALLY LIMITED 1ms The data of Figure 6 is based on T 0.5 J(pk) = 150°C; TC is OR CURRENT @ TC = 25°C (SINGLE PULSE) 5ms variable depending on conditions. Second breakdown pulse SECOND BREAKDOWN LIMITED 0.2 CURVES APPLY BELOW limits are valid for duty cycles to 10% provided TJ(pk) < 150°C. T , COLLECT 0.1 RATED VCEO J(pk) may be calculated from the data in Figure 5. I C TIP120, TIP125 0.05 At high case temperatures, thermal limitations will reduce TIP121, TIP126 the power that can be handled to values less than the TIP122, TIP127 0.02 limitations imposed by second breakdown 1.0 2.0 3.0 5.0 7.0 10 20 30 50 70 100 VCE, COLLECTOR-EMITTER VOLTAGE (VOLTS)
