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.
