Why a gas-discharge tube is an important component for overvoltage protection. The history of spark gaps—predecessors to GDTs—includes a role in famous movies. How a new, compact, surface-mount GDT ...

With all the new, innovative types of components we see, it's interesting to note which “new” devices we routinely use are really updated versions of classics from the early days of electrical design.

The earliest reference to experiments involving lightning was Benjamin Franklin’s kite experiments in 1752. However, it was in 1859 that Yale University described the use of the first spark gap ...
