Detail affected part number list refer to Appendix.
Littelfuse would like to notify you that we will transfer our backend assembly process of Thyristor & Diode products SOT-227 Package to our new inhouse assembly factory in Lipa, Philippines. This brand-new assembly factory is to fulfill our strategy to invest in state-of-the-art power semiconductor assembly capabilities to dramatically improve our service levels to customers. Our target is to build this factory as a world class facility with automated, error proof processes to meet the highest quality standards. Contact our local Sales team in case you would like to understand more about this new factory. Below is the detail changes associate with this Assembly Location change: 1) Silicon Die: No change 2) Backend Assembly Bill of Materials: No change 3) Backend Assembly Process Flow: Some part numbers change from Pad type to Padless type. Refer to PCN report. 4) Backend Assembly Equipment: Equal or better 5) Marking & Labeling: Yes.
SUBJECT: Assembled Device Marking Format Changes and Outer Box/Bag Label Format Changes - Change to the assembled device marking format The change affects the date code and tracking number identification. This change does not affect the form, fit or function of the product. See attached for more details - Change to the box label format: The paper sticker label found on the outer box or bag will see a format change that incorporates the Littelfuse logo along with the IXYS logo. The printed information remains the same (PN, Qty, Lot #, date code, country of origin). The change allows for a improved readability. This change does not affect the form, fit or function of the product. REMARKS: This changes from the original IXYS Corporation marking/labeling format to the new IXYS LLC-USA format is being done to conform to the SAP product management system requirements of our parent company Littelfuse Corporation.
This product is currently unavailable for order and Littelfuse has not yet qualifyed an alternative source. A reinstatement will be issued when product becomes available.As Littelfuse already noticed in previous Pre-PCN# ESW490-42, we are ongoing qualifying alternative source to retain our supply chain due to Russia Sanction. And this letter will advise our latest progress and timeline and we appreciate customer could bear the qualification time to allow Littelfuse presenting best quality product as usual.
