BONDING WIRE LIMIT
THERMAL LIMIT
SECOND BREAKDOWN LIMIT
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 calcu-
lated 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 sec-
ondary breakdown.
