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,
powertemperature derating must be observed for both
steady state and pulse power conditions.
