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 ( tele-

phone 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
