Gas Discharge Tube (GDT) Products
SL1010A Series
SL1010A Series
Description
The SL1010A Series Gas Discharge Tube (GDT) offers
a compact, three-terminal, surface mount component
that’s just 5mm in diameter. It is rated for 10 hits
(±5 repetitions) of a 5kA 8/20µs surge event with a
low off-state capacitance of 1.5pF. Its low arc voltage
parameter of 10V reduces thermal accumulation
during long-term power fault events.

SL1122A Series
SL1122A Series Hybrid
Description
The SL1122A series Hybrid features a high
performance Alpha Gas Plasma Tube in conjunction
with a MOV. These devices are matched so that high
speed pulses are initially clamped by the MOV, then
as the current rises, the transient energy is switched
through the gas tube. The Hybrid offers high levels of
performance on fast rising transients in the domain
of 100V/µs to 10 kV/µs, so eliminates the dv/dt
switching delay normally exhibited by standard GDTs.
These devices are extremely robust and are able to
divert a 10,000 Amp pulse without destruction.
