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.

Revised: 07/30/15 Gas Discharge Tube (GDT) Products 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.
