John, Re: "I am a space systems engineer with over 10 years experience designing the space systems ..." Now that just fills me with confidence about the US space program ... John, you don't know what you are talking about when it comes to FET/CPU reliability. Just as you stated for specified voltage range ... "IF THE Vcc IS WITHIN LIMITS SPECIFIED FOR THE PART, IT IS NOT A FACTOR!" ... I would say the same thing about temperature. As long as the junction temperature stays within specifications, there will be no problem. The difference between changing temperature and voltage is ... junction temperature can be controlled with "heatsink" design, increased Electric fields due to increased voltages cannot be as easily compensated. Make It So, Yousef

Petz, "I have never seen Vcc voltage even mentioned in an S-Level [avionics and space] reliability characterization document." Of course as a software engineer like yourself do not get exposed to all the relevant parameters, and that is understandable. The reason why Vcc is not specified to your awareness is because it is set at manufacturer's guarantee. Devices such as transistors, diodes, capacitors, etc. would have this voltage break down rating heavily specified. Petz, you maybe very good at doing software, but coming down to hardware, you know squat! John.

Petz, Obviously you have skills and qualifications in you area of expertiese. Don't be so foolish as to think your skills carry over to the semiconductor area. Clearly they do not. We wouldn't pretend to tell you how to make a satellite. Don't pretend you know semiconductors. You don't. EP
