Humidity Lifetime for FMM5820QH
The following graph shows the lifetime of moisture resistance for the FMM5820QH. Each
line in the graph indicates the lifetime that is the estimated failure rate of 0.1% at 10 years
(Confidence Level = 90 %) and calculated from the results of pressure cooker (autoclave) bias
test. The horizontal-axis shows typical ambient temperature. The vertical-axis shows relative
humidity. The left side of the area delimited in each line indicates more than 10 years of
lifetime.
Field environmental conditions for operation
In the case that FMM5820QH is mounted in a non-hermetic package, please refer to the
following recommendations.
Note 1. The graph lines are drawn using the operating conditions as shown in the box below.
EUD recommends our customers use FMM5820QH within the left side area
separated by each line in the graph below.
Note 2. Please cut off the drain current by drain bias, not by gate bias.
The humidity lifetime becomes shorter in case of gate cut off operation.
Note 3. Please use FMM5820QH under environmental conditions of no dew condensation.
