Figure 1. Active Region Safe Operating Area
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.
