Figure 13. Thermal Response
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 that can be handled to values less than the limitations
imposed by the secondary breakdown.
