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.
