The Safe Operating Area Curves indicate IC – VCE limits
below which the device will not enter secondary breakdown.
Collector load lines for specific circuits must fall within the ap-
plicable Safe Area to avoid causing a catastrophic failure. To
insure operation below the maximum TJ, power–temperature
derating must be observed for both steady state and pulse
power conditions.
