Vishay PTN-SIL-038-2026-REV-0 - Convert to Copper (Cu) Wire - SQ4284EY

Sep 10, 2026

Notification PTN-SIL-038-2026-REV-0 addresses a material conversion for affected device part numbers from gold (Au) bond wire to copper (Cu) wire. The updated ordering code is SQ4284CEY-T1_GE3, while maintaining identical silicon technology and silicon die design versus SQ4284EY. Sheet AC parameter changes may result from lot-to-lot variation and/or updated characterization methods; device performance in application is stated as not impacted, and the wafer fab location remains unchanged. Timing includes defined last time buy/ship dates and replacement sample availability on request, with relevant qualification and PPAP information available as requested.
