Don't take anything here as being 100% correct. Ask questions if you want me to explain anything.

Snubbers protect the swithcing element by taking the power that usually dissipated on the element and dissipating it elsewhere.

High current with high Vds = high power dissipation. 
So, any point on the upper right of the XY scope = high power = bad.
Points in the lower left = low power = good.

I know that a Faraday cage will protect electronics and electrical equipment from an EMP attack. But there is no way possible to protect the power grid and exposed equipment out and about. Question to any one specially the Engineer types, you know who you are..... 1. Can we build snubbers big enough to protect power stations and power lines?

We have to protect our country from the lunatics out there with nucs itching to send us back to stone age.

Zobel network's normally offer improved performance over a basic diode. The relevant equations for L-R network are: R = coil resistance L =coil inductance C1 = L/R squared. R is simple enough; it equals the relay coil resistance. C1 = L / (R x R). But increased cost over diode
