There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. Safe operating area curves indicate IC − 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 7 is based on TJ(pk) = 150�C; TC is variable depending on conditions. Second breakdown pulse limits are valid for duty cycles to 10% provided TJ(pk) � 150°C. TJ(pk) may be calculated from the data in Figure 6. At high case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. **Figure 7.

**==> picture [63 x 78] intentionally omitted <==** **Figure 13. Typical Mounting Techniques*** 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, ON Semiconductor 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. **http://onsemi.com** **5** **MJF47G** ## **PACKAGE DIMENSIONS** **TO−220 FULLPAK** CASE 221D−03 ISSUE K **==> picture [360 x 203] intentionally omitted <==** **----- Start of picture text -----**
