When operated at this bias condition with a base plate temperature of TBD, the median life is
reduced from TBD to TBD hrs.

Junction operating temperature will directly affect the device median time to failure (MTTF). For
maximum life, it is recommended that junction temperatures be maintained at the lowest possible
levels.
