How good is Nitronex’s reliability?
While different test methodologies and forms of reporting data make direct comparisons difficult, Nitronex believes its reliability is on par with existing technologies such as Si-LDMOS and GaAs pHEMTs. Some common metrics are MTTF (mean-time-to-failure). In this case Nitronex shows a MTTF >10 million hours at an operating temperature of 150°C and a drain voltage of 28V. Another metric is drift over 20 years of operating life. Here Nitronex has demonstrated <6% drift in Imax when operated at 200°C and 28V. Finally the robustness has been demonstrated with ESD results showing HBM ratings >1000V for the NPT35050 device and the ability to survive VSWR mismatches as high as 20:1.
