Figure 14. Active Region Safe Operating Area
The safe operating area curves indicate I C –V CE limits of
thetransistor 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 limita-
tions imposed by the secondary breakdown.
