Customer Information about SOT223 supply situation and Improvement Plan 2017/18 - Update
May 08, 2017

Dear Customer,

As we already informed 2 month ago in March, the Market demand of discrete semiconductor in SOT223 package has increased sharply, mainly driven by automotive and mobile markets. This situation exceeds our available capacity. Accordingly we already announced our increased delivery lead time of 26 weeks in FEB 2017.

Above described situation remains unchanged and WeEn Semiconductors expects this situation to continue until end of Q1'2018. We plan to update on supply situation and our progress of improvement action on a quarterly base next in June 2017.

We are aware that this supply situation is far from being satisfying and we increased our efforts to ease this situation as soon as possible:

  • A Task Force under the leadership of the WeEn COO has been set up to speed up the process of building additional capacities thru qualifying alternative assembly site. Assembly Partner has been identified, Lead Products are in testing stage for Qualification
  • We are preparing the PCN distribution for beginning of Q3 and we appreciate customer to qualify our new assembly site with high priority We

We thank you for your confidence and appreciate your support and understanding. Your WeEn regional manager will answer any question you might have and assist you in managing this situation.


Yours Sincerely,

Markus Mosen
CEO of WeEn Semiconductor
