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 dissipa- tion than the curves indicate. The data of Figure 4 is based on TJ(pk) = 175_C, TC is variable dependIng on conditions. Second breakdown pulse limits are valid for duty cycles to 10% provided TJ(pk) v 175_C. TJ(pk) may be calculated from the data in Figure 3. At high case temperatures thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. 20 100 140 260 0 180 220 60 VCE, COLLECTOR–EMITTER VOLTAGE (VOLTS) 20 0 Figure 5.

Under these conditions the collector voltage must be hold to a safe level at or below a specific value of collector current. This can be accomplished by several means such as active clamping, RC snubbing, load line shaping, etc. The safe level for these devices is specified as Reverse Bias Safe Operating Area and represents the voltage–current conditions during re- verse biased turn–off. This rating is verified under clamped conditions so that the device is never subjected to an ava- lanche mode. Figure 5 gives ROSOA characteristics. |
