Datasheet
**Gas Discharge Tubes** SL1011A and SL1411A Series ## SL1011A and SL1411A Series ## ~~cj@®AW~~ **RoHS** ## ~~**Description**~~ The SL1011A and SL1411A series provides high levels of protection against fast rising transients in the 100V/µs to 1kV/µs range usually caused by lightning disturbances. The SL1011A and SL1411A series offers low capacitance (< 1.5pf) which provides low insertion loss at high frequencies. SL1011A offers 5kA protection without destruction whereas the SL1411A offer 10kA surge protection without destruction (maximum single surge of 12kA @ 8/20µs). **==> picture [259 x 70] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approvals<br>es «=<br>Agency Agency File Number<br>E128662<br>i<br>**----- End of picture text -----**<br> ## ~~**Features**~~ - Lead-free and RoHS • 5kA (SL1011A) or compliant 10kA (SL1411A) surge - • Low insertion loss capability tested with 8/20μs pulse as - • Excellent response to defined by IEC 61000fast rising transients 4-5 2nd Edition - 4-5 2nd Edition - Ultra low capacitance ~~**2 Electrode GDT Graphical Symbol** pe~~ ## ~~**Applications**~~ - Broadband equipment - ADSL equipment - XDSL equipment - Satellite and CATV equipment - General telecom equipment ## **Additional Information** **==> picture [198 x 74] intentionally omitted <==** **----- Start of picture text -----**<br> Datasheet Resources Samples<br>SL1011A SL1011A SL1011ASL1011A<br>Gi<br>Datasheet Resources Samples<br>SL1411A SL1411A SL1411ASL1411A<br>**----- End of picture text -----**<br> © 2020 Littelfuse, Inc.

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
