These ratings represent the maximum operable values for this device. Combinations of supply voltage, supply current, input power, and output power shall not exceed PD. PD is the power dissipation allowed in order to reach a channel temperature of 150C with a package base temperature of 70C. When operated at this power dissipation with a baseplate temperature of 70C, the MTTF is reduced from 5.3E+6 to 1.0E+6 hours. These ratings apply to each individual FET. Junction operating temperature will directly affect the device median time to failure (TM). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.
