Unless otherwise specified, the following specifications apply over the operating ambient temperature 0°C
otherwise noted and the following test conditions: T
characteristics only. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the
ambient temperature.
Note 1: The Temperature Extremes are Guaranteed but not 100% Production Tested.
