Gas Discharge Tubes
High Performance Beta Range
RoHS Pb Greentube SL1002 Series Gas Plasma Arresters
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
10/560µs waveform 100A test.
Applications:
• Broadband equipment.
• ADSL equipment.
• XDSL equipment.
• Satellite and CATV equipment.
• General telecom equipment.

Greentube SL1021A Series Gas Plasma Arresters
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
IEC 61000-4-5
• 20,000 A single shot surge capability tested with 8/20µs
pulse as defined by IEC 61000-4-5
• Available with thermal failsafe option
(add ‘F’ or ‘S’ suffix to part number)
• ROHS Compliant
Applications:
• Broadband equipment.
• ADSL equipment.
• XDSL equipment.
• Satellite and CATV equipment.
• General telecom equipment.

High Performance Alpha Range

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
• SAD ensures short circuit failure mode in the event of severe
transient overload.
• Thermal failsafe.
Applications:
• MDF protection
• Alarm panels.
• ADSL equipment.
• XDSL equipment.
• General Telecom Equipment

Greentube SL1026 Series Gas Plasma Arresters
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.
FEATURES
• RoHS compliant
• 55 kA surge capability (single shot) tested with 8/20µS pulse
as defined by IEC 61000-4-5
• 40 kA surge capability (repetitive)
• Will protect against Trapezoidal waveforms as specified in
RIA 12.
• Will protect against capacitor discharge voltage transient
waveforms as specified in RIA 12.
• Will protect against double exponential voltage transient
waveforms as specified in IEC 571.
Applications:
• Signaling equipment.
• Communication equipment
• Control gear.
• Trackside cabinets.
• Cell phone base stations
