1 _) f8 D- E" K1 N8 ~ 9 N Failure modes It is always very difficult to be certain of exactly what caused any one failure: the problem is that failures are very difficult to promote in any well designed controller, and customers are not usually aware of exactly what happened to cause...
In the end, the combination failure modes of the over current and over voltage in real application are discussed. Key words : over current;over voltage;hot spot;linear zone;electrical over stress 目前,功率MOSFET管广泛地应用于开关电源系统及其他功率电子电路中。实际应用中,特别是在一些极端的边界条件...

This paper summarizes the relevant research results of MOSFET lifetime model,classifies MOSFET failure modes, and establishes the corresponding MOSFET lifetime model of different failure modes,and further summarizes the failure criteria and experimental verification methods of each lifetime model.Keywords: ...
This has specific consequences on all failure modes which are caused by those particular types of defects. Using a simple model for hot carrier interface state generation and a percolation model for oxide breakdown, the roughly Weibull statistics thus generated are easily interpreted in terms of a ...
