The safe operating area curves indicate IC–VCE limits of the
transistor that must be observed for reliable operation. Collector load
lines for specific circuits must fall below the limits indicated by the
applicable curve.
The data of Figure 14 is based upon TJ(pk) = 150°C; TC or TA is
variable depending upon conditions. Pulse curves are valid for duty
cycles to 10% provided TJ(pk) ≤ 150°C. TJ(pk) may be calculated from
the data in Figure 13. At high case or ambient temperatures, thermal
limitations will reduce the power than can be handled to values less
than the limitations imposed by second breakdown.
