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
applicable 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.
