IXYS product discontinuation

Littelfuse has this month announced the discontinuation of screws attachments for TO-240 bipolar modules in Asia, America, Europe, Middle East and Africa (EMEA). Starting 1st July 2021, the production of TO-240 packages has been fully moved to the Philippines (Lipa) factory. Due to limited resources of the Littelfuse EMEA warehouse, the TO-240 modules will no longer be attached with screws as complimentary accessories for EMEA customers.

Effective date: 15th September 2021
