White Horse Laboratories: Week 47 Quality Report
Electrical Testing – 62% Passed
Physical Inspection – 67% Accepted
Week 47 saw a few more suspect “Infineon” devices and other discrete devices exhibiting extremely high failure rates, indicating clone devices are continuing their prevalence.
Be on the lookout, though, for the following high risk devices*:
Infineon BSP75NL, 50% failure – high threshold and clamped breakdown voltages
Infineon TLE5206-G, 82% failure - clamped outputs with the error flag active.
Atmel AT29C040A-90TU, 15% failure – program and verify error.
Atmel AT91SAM7S256-AU, 100% failure - blank-check error after erasing.
International Rectifier HFA16TB120PBF, 6% failure - high reverse current, Ir, and low breakdown voltage, Vbr.
International Rectifier IRAMS10UP60B, 12% failure – low bootstrap voltage.
Toshiba USF8G48, 12% failure – high repetitive peak off-state current, Idrm, and repetitive peak referse current, Irrm.
Anachip PEEL18CV82J-25L, 100% failure – program and verify error.
Maxim MAX4678EUE+T, 100% failure – high on resistance.
Teccor P3300AA61 – 100% failure – high VT (part not switching) and high IS (part not turning on).
* Note: high risk is defined as devices with over a 5% failure rate in electrical testing.
Quality drives a company’s reputation, its bottom line and above all, its value.
