Implementation of change:
Expected 1st Device Shipment Date: 2008/01/29
Earliest Year/Work Week of Changed Product: 0805
Change Type Description: Lead Frame Dimensions (Internal and External)
Description of Change (From): Current TO-220 heatsink and die attach pad thickness of
1.30mm.
Description of Change (To): New TO-220 heatsink and die attach pad thickness will be
0.51mm. There is no change in heatsink and die attach pad material. Conversion of heatsink
thickness will be done on a part by part basis starting WW05 of 2008 to prevent mixing of
product with different heat sink dimensions in shipments during the transition period.
Reason for Change : Enhancement of leadframe design to improve package mechanical
performance and support additional demand for various TO-220 products to improve our
service to customers. There is insignificant difference in product thermal performance.
Qual/REL Plan Numbers : Q20070208
