- Home gate way AGENCY AGENCY FILE NUMBER E128662 Agency Approvals 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.
