F.Giacosa Reliability Engineer G. Di Leo Reliability & F/A Manager Date Oct 2002 Issued by Reliability Laboratory Page 2 of 2 INTERNATIONAL RECTIFIER 1. Introduction and Purpose: The purpose of this qualification program is to produce test data and relevant information to confirm that the 25 Amps. RBV bridge series devices, meet the requirements for Market Introduction and IR internal Reliability Standards. The test vehicles are IR25XB06. The data and report are generated by IRCI Reliability Laboratory. 2. Issue: The results collected in this report are sufficient to release a Final Qualification Approval of above mentioned devices. The Final Qualification Approval is justified by environmental testing, presented in this report, which ensures that the product under consideration fulfils the requirements for Market Introduction and IRCI's reliability requirements. The Final Qualification is released for part number under mentioned: All 25 Amp RBV Bridge series devices 3. Process Description: The product family under consideration uses RBV package and standard assembly process. 4. Executive Summary: Environmental testing was performed on 3 lots. The lot was assembled in IR25XB06. Environmental testing included: Temperature Cycling Test (T/C). High Temperature Blocking Life Test (HTRB) 5.
