Theoretically single lightning strike produce 20,000 to 40,000 Ampere and about 200 Mega volts (MV) .It enough to generated a temperature about 4 times hotter than the surface of the sun.

In the market,some of surge protectors are designed to cut out  if a surge value exceeds 60,000 ampere to protected the sensitive equipment from defected. read more
