Re: E.S. of plastic xstr case
Dear John: Well, maybe not the ten millionth, but at least the umpteenth! We are an A2LA Accredited Lab in Washington State ( in the quiet country midway between Seattle and Vancouver, British Columbia). Wyle indeed works here, and is quite proficient at EMI mitigation. During coffee breaks I can see him from my office window -- running and frolicking with Eagles, Cattle, and yes, occasionally other Coyotes.

Re: E.S. of plastic xstr case
Brian: Transistor and Integrated Circuit "plastic" encapsulants usually are some recipe of Epoxy Novolac. I'd suggest doing a Google search for [Epoxy Novolac +electrical characteristics]. Or, do an end run on a manufacturer. You might try calling Philips Semiconductor on Arques Avenue in Sunnyvale, California. Ask for Bill Hobdy. He's an epoxy expert there. I worked with him for many years, so use my name if it helps get through the maze. Good luck!

But I cannot find manufacturers' specs listing the dielectric strength of the plastic case (e.g., TO-0220). Am I overlooking an obvious data source? They must design this in, because all of the FETs that I have tested do ok up to approx 2500Vdc. thanks much. R/S, Brian
