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.
