Gas Discharge Tube (GDT) Products

SL1021A/B, SL1024A/B and PMT8 Series

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.

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.
