1 Littelfuse, Inc West Higgins Road, Suite 500 Chicago, IL USA (773) May 17 th, 2018 Littelfuse TVS STD DO-214AB Package Capacity Expansion Notification Letter To: Our Valued Customers In order to support growing demand, Littelfuse SBU (Semiconductor Business Unit) completed TVS STD DO-214AB package capacity expansion qualification. With this new capacity expansion line released, there will have more capacity to support growing demand of TVS STD DO-214AB package. This DO-214AB package backend new line for capacity expansion is installed in Littelfuse Semiconductor Wuxi China, and is planned to have production since June As rolling change, please expect to receive products manufactured by either current line or new capacity expansion automation line. The affected part numbers as attached excel file, have been fully qualified in accordance with established performance and reliability criteria. The next few pages summarize the qualification results for your reference please. There are no changes on FIT, form, function and reliability of the finished product. Form, fit, function, reliability changes: None Part number changes: None Effective date: June 2018 or sooner Replacement products: N/A Last time buy: N/A This communication letter is for your information and acknowledgement. If you have any other questions or concerns, please contact your local sales team or product team below for further assistance. We highly value your business and look forward to assisting you whenever possible. Sincerely, Jenny Chen Assistant Product Manager Commercial TVS Products Tel: Ext 7779 To: Those who may concern

MTBF Calculation Estimate of Failure Rate, MTBF, FITS for a Given Operation Temperature (See note) Temp % FR/khrs MTBF (K) FITS Note: The Mean-Time-Between-Failure (MTBF) in hours and the percent failure rate per 1000 hours (%FR/khr) are computed at a 60% confidence level using the chi square method and the Arrhenius derating model for various junction operating temperatures. For the calculations, a value of 1 ev was used for the activation energy. 4. Conclusion According to the above qualification test results, Littelfuse concluded that TVS STD DO-214AB package capacity expansion project has been fully qualified and released to production.
