Littelfuse, Inc. has introduced the SL1010A Series Gas Discharge Tube (GDT), a small-footprint, three-terminal, surface-mount component that protects a broad range of communication equipment from damage due to fast-rising transients typically caused by lightning disturbances. The SL1010A Series GDT is rated to withstand lightning surge currents of 5kA at 8/20µs. Its low off-state capacitance of less than 1.5pF minimizes insertion loss and helps preserve signal integrity in data communication lines. Its low arc voltage (about 10V) reduces thermal accumulation during long-term power faults.

At just five-millimeters in diameter, the three-terminal SL1010A Series GDT is designed for small form factor applications that require both high energy withstanding capability and a compact footprint. Applications include new telecommunication system designs with miniaturized components, last mile telecommunication equipment such as very fast DSL, industrial RS-485, Power over Ethernet, and home gateways.

The SL1010A Series GDT offers these key benefits: High energy withstanding in a small body makes the SL1010A Series ideal for small form factor applications with minimum footprint requirements. With less than 1.5pF of off-state capacitance, the SL1010A GDT ensures minimal insertion loss and helps preserve signal integrity. Low arc voltage avoids thermal accumulation due to high on-state voltages. Three-terminal design with symmetry for Tip/Ring/Gnd reduces the frequency of longitudinal to transverse mode conversions that occur during surge events. And a RoHS-compliant, lead-free design makes the SL1010A Series environmentally friendly. The SL1010A Series GDT is available in quantities of 900 in tape and reel packaging.
