Littelfuse, Inc. Datasheets for Gas Discharge Tubes (GDT)

Gas discharge tubes (GDT) or gas tube arrestors (GTA) provide protection against voltage and current surges in electronic and electrical equipment. They include spark gaps, simple devices with two or three conducting electrodes separated by a gap filled with a gas such as air.
