The safe operating area curves indicate IC−VCE lim-

its of the transistor that must be observed for reliable oper-

ation. 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.
