Reliability Data Sheet
Description
The Avago Technologies reliability data shown represents
the high reliability class of this product family. Both of
the products listed use the same LEDs, ICs, DLA approved
packaging materials, processes, stress conditions and
testing per MIL-PRF-38534. Additionally, Avago Technol-
ogies internal processes, material specifications, design
standards, and statistical process controls are utilized.
The data is NOT TRANSFERABLE TO OTHER MANUFAC-
TURERS’ SIMILAR PART TYPES.
Operating Life Test
For valid system reliability calculations it is necessary to
adjust for the time when the system is not in operation.
Note that if you are using MIL-HDBK-217 for predicting
component reliability, the results may not be compara-
ble to those given in Table 2 due to different conditions
and factors that have been accounted for in MIL-HDBK-
217. For example, it is unlikely that your application will
exercise all available channels at full rated power with the
LED(s) always ON as Avago Technologies testing does.
Thus, your application total power and duty cycle must
be carefully considered when comparing Table 2 to pre-
dictions using MIL-HDBK-217.

Definition of Failure
Inability to switch, i.e. “functional failure” is the defi-
nition of failure in this data sheet. Specifically, failure
occurs when the device fails to switch ON with 2 times
the minimum recommended drive current (but not
exceeding the max rating) or fails to switch off when
there is no input current
Application Information
The data of Table 1 and 2 were obtained on MIL-PRF-
38534 screened devices with high temperature operating
life duration up to 5000 hours. An exponential (random)
failure distribution is assumed, expressed in units of FIT
(failures per billion device hours) are only defined in the
random failure portion of the reliability curve.
Failure Rate Projections
The demonstrated point mean time to failure (MTTF) is
measured at the absolute maximum stress condition. The
failure rate projections in Table 2 uses the Arrhenius ac-
celeration relationship, where a 0.43 eV activation energy
is used as in the hybrid section of MIL-HDBK-217.
Environmental Testing
All high reliability hermetic optocouplers listed meet the
100% screening and quality conformance inspection
testing of MIL-PRF-38534 Class H.
