GaN Systems and its partners from the global automotive, industrial, and HiRel industries have taken the lifetime and reliability challenge on to create an approach that draws considerations from JEDEC and AEC-Q and an understanding of industry challenges in qualification testing. The GaN Systems’ whitepaper reviews this, and outlines:
- The collaborative approach strategy which looks at device failure modes, transistor test design, and manufacturing process feedback.
- Enhanced product qualification processes using JEDEC and AEC-Q101 tests as a baseline and additional test methods to account for differences between silicon and GaN, and test results of GaN Systems’ devices.
- Definition of lifetime models by determining failure mechanisms and applying a Failure Mode and Effects Analysis (FMEA), builds parts, and Test-to-Failure processes. Test results of GaN Systems’ devices are also shown.
“The assumption that GaN is unproven or unreliable is no longer in question. In the last few years, we’ve seen global companies continue to use and introduce innovative products and systems using GaN Systems power semiconductors as the basis for design,” said Jim Witham, CEO at GaN Systems. “It is clear that the work we have done with our customers to create an enhanced reliability test set ensures that GaN Systems’ devices demonstrate industry leading performance and lifetime in the most challenging environments.”
