1. 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 failsafe clip. Please refer to the electrical specifications, dimension and packaging options section of this document for additional information. 

SL1021A/B and SL1024A/B Series:

SL1021A/B and SL1024A/B series GDTs are designed to offer high levels of performance on fast rising transients in the range of 100V/μS to 1KV/μS, which are those most likely created by induced lightning disturbances. These devices feature ultra low capacitance (typically 1.5pF or less) and are extremely robust with SL102xA devices able to divert a 10,000 Amp pulse without destruction, and SL102xB suffix devices able to divert a 20,000 Amp pulse without destruction. These series offer optimized internal geometry which provide low insertion loss at high frequencies, ideal for the protection of broadband and other high speed transmission equipment.

PMT8 Series:

PMT8 GDT's are telecom grade devices designed to meet the recommendations in CCITT-K12 and Bellcore GR-1361-CORE. The three electrode configuration is used in applications where simultaneous crowbar action of two signal lines is required.
