®
The Broadband Optimized™ SL1002 series has been especially
developed for use in broadband equipment. Unique design features offer high levels of performance on fast rising transients in
the domain of 100V/µS to 1KV/µS, which are those most likely
from induced Lightning disturbances. These devices have Ultra
low capacitance (typically 1.2pF or less) and present insignificant
signal losses up to 1.5GHz. These devices are extremely robust
and are able to divert a 5000A pulse without destruction. For AC
Power Cross of long duration, overcurrent protection is recommended.
FEATURES
• RoHS compliant
• Ultra Low Insertion Loss
• Surface mountable
• 5KA surge capability tested with 8/20µS pulse
as defined by IEC 61000-4-5
• Excellent response to fast rising transients.
• Can be used to meet Telcordia GR1089
without series resistance
• 10/700 6KV capability, as per ITUT k.21, enhanced test level
• 2000 Amp 2/10µS surge rating
• Meets FCC part 68 10/160µs waveform, 200A test and
8
10/560µs waveform 100A test.

®
The SL1021A series offers high levels of performance on fast rising transients in the domain of 100V/µS to 1KV/µS, which are
those most likely from induced Lightning disturbances. The
SL1021A series also features ultra low capacitance (typically 1pF
or less) and optimised internal geometry which provides low
insertion loss at high frequencies, so are ideal for the protection
of broadband equipment. These devices are extremely robust
and are able to divert a 10,000Amp pulse without destruction.
FEATURES
• RoHS compliant except ‘RS’ suffix
• Low insertion loss
• Excellent response to fast rising transients.
• Ultra low capacitance.
• 10KA surge capability tested with 8/20µs pulse as defined by

High Performance Alpha Range
RoHS
Greentube™ SL1122A Series Hybrid Gas Plasma Arresters
®
The SL1122 series Hybrid features a high performance Alpha Gas
Plasma Tube in conjunction with a high speed Silicon Avalanche
Diode ( SAD ). These devices are matched so that High speed
pulses are initially clamped by the SAD, 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 GDT’s. These
devices are extremely robust and are able to divert a 10,000Amp
pulse without destruction, so are ideal for central office ( telephone exchange ) protection.
FEATURES
• RoHs Compliant
• Excellent response to fast rising transients.
• Flat response up to 10KV/µS.
• 10KA surge capability tested with 8/20µS pulse as defined by
IEC 61000-4-5

Greentube™ SL1026 Series Gas Plasma Arresters
Pb
®
The SL1026 series is a heavy-duty transient suppresser using Gas
Plasma technology. In response to a transient voltage which
exceeds the fixed breakover voltage (selected according to part
number) the device changes from a very high impedance state to
a low impedance state, there by conducting harmful current
away from the protected system. The design is optimized for the
protection of electrical and electronic equipment employed in
Railway systems: carefully designed geometry ensures the device
does not become a short circuit in the event of a failure due to
conditions and events beyond the design criteria. An electrical
mounting clip (PN SL1053 ) is available to aid mounting and connection. A mounting plate (PN SL 1056) is also available which
accepts 10 SL1053’s. Mounting of the clips to the plate provides a
common ground connection; the plate can then be connected to
a suitable ground via the screw terminal.
