Update from Week 26
  
In last week's report, Week 26, we listed a Microsemi device with date code 1052 that had a 95% failure rate for high forward voltage; however, the part number was inadvertantly left off of the listing. The part number is LSM150J3/TR.
  
We also listed an Infineon device with date code 1018 that had a 6% failure for high off-state drain current, Id(off). The part number listed was BSP14PL6906. The correct part number is BSP149L6906.
  
Our apologies for any inconvenience.
  
Notes:

1. Statistics are calculated as a percentage of all lots dispositioned within the given time period.

2. "Accept" is defined as customer acceptance of report device condition.

3. "Pass" is defined as meeting electrical parameters defined by the agreed upon test plan.

 
We hope you find this report informative and usefull for your organization.

 

All the best,
