SL1021A/B 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 Series:
Agency Approvals
SL1021A/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.
AGENCY
AGENCY FILE NUMBER
E128662
These devices feature ultra low capacitance (typically
1.5pF or less) and are extremely robust with SL1021A
devices able to divert a 10,000 Amp pulse without
destruction, and SL1021B suffix devices able to divert
a 20,000 Amp pulse without destruction.

b = RING
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.
