My old Seimens datasheet shows that to be 145 VDC +/- 20% breakdown,
<750 V impulse breakdown (100 V/us impulse) and <1100 V impulse
breakdown (10,000V/us risetime impulse). It can handle 5000 amps for
a single impulse, with approxiamately 200 shots before failure. Its
AC current rating is 20 Amps RMS when first breakdown (for 11
cycles), discharging 35 amps followon. It should extinguish on the
next zero crossing, so this is only usually 1/2 cycle or so - unless
it is grossely overdriven. It is specifically made for AC
applications, like across AC power circuits for protection. Things
like CATV amplifiers and remote 24VAC systems outdoors, that have ac
power feeder.
As far as knowing the gap measurement, or material, it doesn't say.
It has some 'rare' gas inside but not radioactive as far as I can
tell. Why do you need to know those parameters?
