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. Figure 3 is based on JEDEC registered Data. Second breakdown pulse limits are valid for duty cycles to 10% provided TJ(pk) < 200_C. TJ(pk) may be calculated from the data of Figure 2. Using data of Figure 2 and the pulse power limits of Figure 3, TJ(pk) will be found to be less than TJ(max) for pulse widths of 1 ms and less. When using ON Semiconductor transistors, it is permissible to increase the pulse power limits until limited by TJ(max). |
