Description
GDT circuit protection devices dissipate electrical surge energy safely within a contained plasma gas. Commonly used to help protect sensitive telecom and networking equipment and lines, GDTs protect from damage that may result from lightning strikes and equipment switching operations.
The Littelfuse GDT series described in this document are available in a variety of leaded and surface mount forms and offered with and without optional fail safe clip. Please refer to the electrical specifications, dimension and packaging options section of this document for additional information.
