DS21354

03/11/2004 RELIABILITY REPORT FOR DS21354, Rev B2 Dallas Semiconductor 4401 South Beltwood Parkway Dallas, TX 75244-3292 Prepared by: Ken Wendel Reliability Engineering Manager Dallas Semiconductor 4401 South Beltwood Pkwy. Dallas, TX 75244-3292 Email : [email protected] ph: 972-371-3726 fax: 972-371-6016 mbl: 214-435-6610 Conclusion: The following qualification successfully meets the quality and reliability standards required of all Dallas Semiconductor products and processes: DS21354, Rev B2 In addition, Dallas Semiconductor's continuous reliability monitor program ensures that all outgoing product will continue to meet Maxim's quality and reliability standards. The current status of the reliability monitor program can be viewed at http://www.maxim-ic.com/TechSupport /dsreliability.html. Device Description: A description of this device can be found in the product data sheet. You can find the product data sheet at http://dbserv.maxim-ic.com/l_datasheet3.cfm. Reliability Derating: The Arrhenius model will be used to determine the acceleration factor for failure mechanisms that are temperature accelerated. AfT = exp((Ea/k)*(1/Tu - 1/Ts)) = tu/ts AfT = Acceleration factor due to Temperature tu = Time at use temperature (e.g. 55°C) ts = Time at stress temperature (e.g. 125°C) k = Boltzmann’s Constant (8.617 x 10-5 eV/°K) Tu = Temperature at Use (°K) Ts = Temperature at Stress (°K) Ea = Activation Energy (e.g. 0.7 ev) The activation energy of the failure mechanism is ...
