Gas Discharge Tubes

Littelfuse Gas Discharge Tubes (GDTs) are designed for high-voltage transient surge protection in small devices. Littelfuse GDTs are designed to dissipate large amounts of energy and are ideal for lightning surge protection. GDTs are widely applied to outdoor telecommunications equipment. These Littelfuse devices are available in leaded and surface-mount configurations.
