Polyphaser has many technical papers on this and they ARE the experts considering they provide equipment to the military.http://www.transtector.com/products/emp-emi-protection/e3pm there is a ton of good info on their pages about surge and emp suppression!

If you want to design your own these are some of the fastest surge suppression devices on the market, typically 1ms response time http://www.digikey.com/products/en?v=18&keywords=diodes+15kpa&WT.z_slp_buy=littelfuse_tvsdiodes you need to keep all leads in the design as short as possible at those speeds!

Hi Mary,

Did you mean 1ms?  From the first datasheet on your link: "Fast response time: typically less than 1.0ps from 0 Volts to BV min"

They list 1ms in some spots an ps in another, looking at the curves 1ms is for full current, 1ps is for the start time... at least that is how I read it. Still a super fast device and for higher surge run 4 in parallel. As mentioned at these speeds lead lengths and capacitance to surrounding objects makes a huge difference!
