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 speci?cations,
dimension and packaging options section of this
document for additional information.

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.
3 Electrode GDT Graphical Symbol
These devices feature ultra low capacitance (typically
1.5pF or less) and are extremely robust with SL102xA

destruction, and SL102xB suf?x devices able to divert
a 20,000 Amp pulse without destruction.
Features

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:
? RoHS compliant
? Low insertion loss
? Excellent response to
fast rising transients
? Ultra low capacitance
? 10KA (A suf?x devices) /

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