Pulse Test: Pulse Width ≤ 300 ms, Duty Cycle ≤ 2.0%. 10 The Safe Operating Area Curves indicate IC−VCE limits 100 ms below which the device will not enter secondary breakdown. Collector load lines for specific circuits must fall within the 3 1 ms (AMP) applicable Safe Area to avoid causing a catastrophic failure. 5 ms To insure operation below the maximum TJ, TJ = 150°C dc power−temperature derating must be observed for both 1 steady state and pulse power conditions.
