Reliability Data Sheet

Introduction

Agilent Technologies’ quality

system includes an ongoing

reliability monitor program to

generate a data base from which

this reliability data sheet is

published.

Transmitter Reliability

The HFBR- 15xx transmitters

incorporate a GaAsP LED emitter

and an optical lens system. The

molded plastic lens of the package

increases the power transmitted to

the fiber.

High Temperature Operating Life

(HTOL) is used to characterize

transmitter reliability in severe

applications over time. The stress

conditions in Agilent’s reliability

testing are accelerated using a

150 mA peak forward current at

1 kHz square wave with 50% duty

factor at 85°C.

Reliability performance observed

on HFBR-1521 applies to the other

HFBR-15xx part numbers listed

above by physical similarity.

Temperature cycling is also

performed in reliability monitor

testing. Table 5 shows available

results on other reliability tests.

The data in Table 5 not included in

Agilent’s ongoing reliability

monitor testing plan was taken

from device or process

qualification.

Reliability Prediction Model

The reliability prediction model

used to project failure rate and

mean time to failure (MTTF) at

various temperatures shown in the

second table assumes an

exponential cumulative failure

function (constant failure rate).

The Arrhenius temperature de-

rating equation is used. Agilent

assumes no failure mechanism

change between stress and use

conditions. A conservative

activation energy of 0.43 eV was

used and is derived from

MIL-HDBK-217 for hybrid devices.

Confidence intervals are based

upon the chi-squared prediction

method associated with

exponential distributions.
