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. 1.0 2.0 3.0 5.0 7.0 10 20 30 70 100 50 VCE, COLLECTOR-EMITTER VOLTAGE (VOLTS) VCE , COLLECTOR-EMITTER VOLTAGE (VOLTS) Figure 1.
