White Horse Laboratories Week 27 Counterfeit Detection Report

White Horse Laboratories Week 27 Counterfeit Detection ReportIn 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.
