Gas Discharge Tubes SL1010A Series SL1010A Series RoHS 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.
