Forward Bias Safe Operating Area Figure 16. Reverse Bias Switching Safe Operating Area There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. Safe operating area curves indicate I C - VCE limits of the transistor that must be observed for reliable operation; i.e., the transistor must not be subjected to greater dissipation than the curves indicate. The data of Figure 15 is based on TC = 25C; TJ(pk) is variable depending on power level. Second breakdown pulse limits are valid for duty cycles to 10% but must be derated when TC 25C. Second breakdown limitations do not derate the same as thermal limitations. Allowable current at the voltages shown in Figure 15 may be found at any case temperature by using the appropriate curve on Figure 17. TJ(pk) may be calculated from the data in Figures 20 and 21. At any case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. For inductive loads, high voltage and current must be sustained simultaneously during turn-off with the base-to-emitter junction reverse-biased. The safe level is specified as a reverse-biased safe operating area (Figure 16). This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode. 5 1.0 POWER DERATING FACTOR SECOND BREAKDOWN DERATING 0.8 0.6 0.4 THERMAL DERATING 0.2 0 20 40 60 80 100 120 140 160 TC, CASE TEMPERATURE (C) Figure 17.

Typical Mounting Techniques for Isolated Package Laboratory tests on a limited number of samples indicate, when using the screw and compression washer mounting technique, a screw torque of 6 to 8 in . lbs is sufficient to provide maximum power dissipation capability. The compression washer helps to maintain a constant pressure on the package over time and during large temperature excursions. Destructive laboratory tests show that using a hex head 4-40 screw, without washers, and applying a torque in excess of 20 in . lbs will cause the plastic to crack around the mounting hole, resulting in a loss of isolation capability. Additional tests on slotted 4-40 screws indicate that the screw slot fails between 15 to 20 in . lbs without adversely affecting the package. However, in order to positively ensure the package integrity of the fully isolated device, Motorola does not recommend exceeding 10 in . lbs of mounting torque under any mounting conditions. ** For more information about mounting power semiconductors see Application Note AN1040.
