The safe operating area curves indicate I_C–V_CE 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 T_J(pk) = 150°C; T_C or T_A
is variable depending upon conditions. Pulse curves are valid
for duty cycles to 10% provided T_J(pk) ≤ 150°C. T_J(pk) may be
calculated from the data in Figure 13. At high case or ambient
temperatures, thermal limitations will reduce the power that can
be handled to values less than the limitations imposed by the
secondary breakdown.
