Reliability Data
Description
The following cumulative test
results have been obtained from
testing performed at Agilent
Optoelectronics Division in
accordance with the latest
revision of MIL- STD-883.
Agilent tests parts at the absolute
maximum rated conditions
recommended for the device. The
actual performance you obtain
from HP parts depends on the
electrical and environmental
characteristics of your application

Failure Rate Prediction
The failure rate of semiconductor
devices is determined by the
junction temperature of the
device. The relationship between
ambient temperature and actual
junction temperature is given by
the following:
T

but will probably be better than
the performance outlined in
Table 1.
P
AVG
= average power dissipated
in watts
The estimated MTBF and failure
rate at temperatures lower than
the actual stress temperature can
be determined by using an
Arrhenius model for temperature
acceleration. Results of such
calculations are shown in the
table below using an activation
energy of 0.43 eV (reference
MIL-HDBK-217).
