Notes:

1. Operation in excess of any one of these conditions may result in permanent damage to this device. Functional operation at or near these limitations

will change to may signiﬁcantly reduce the lifetime of the device.

2. Combinations of supply voltage, drain current, input power, and output power shall not exceed PD.

3. When operated at this condition with a base plate temperature of 85°C, the median time to failure (MTTF) is signiﬁcantly reduced.

4. These ratings apply to each individual FET.

5. The operating channel temperature will directly aﬀect the device MTTF. For maximum life, it is recommended that junction temperatures be

maintained at the lowest possible levels.
