Omega Rage RoHS Pb Greentube™ SL1024A Series Gas Plasma Arrester ® The SL1024A series offers high levels of current handling on fast rising transients created by induced Lightning disturbances. These devices are extremely robust and are able to divert pulses of 10,000A. The SL1024A also features ultra low capacitance (typically 1pf or less) making them ideal for the protection of high-speed transmission equipment. FEATURES • RoHS compliant except ‘RS’ suffix • Low insertion loss • Excellent response to fast rising transients. • Ultra low capacitance. • 10KA surge capability tested with 8/20µs pulse as defined by IEC 61000-4-5 • Available with thermal failsafe option (add ‘F’ or ‘S’ suffix to part number) 8 • Broadband equipment. a GAS DISCHARGE TUBES Applications: b • ADSL equipment. • XDSL equipment. • Satellite and CATV equipment. e • Splitters • General telecom equipment. 3 ELECTRODE GDT a=TIP b=RING e=GROUND (centre electrode) GRAPHICAL SYMBOL ORDERING INFORMATION SL 1024 A Voltage Pin Configuration (See Mechanical Drawings) Failsafe Optio n F=Plastic S=Solder w w w. l i t t e l f u s e . c o m 342 Gas Discharge Tubes Omega Range RoHS Pb Greentube™ SL1024A Series Gas Plasma Arresters ® LITTELFUSE 3 TERMINAL ARRESTER SERIES TOTALLY NON-RADIOACTIVE, UL RECOGNIZED DC Breakover Voltage Min-Max7 @ 100V/sec DC (V) Voltage(V) Part Number Max Max Repetitive Single Impulse Alternating Impulse Discharge Discharge Discharge Current Current Current1,3 (kA) (kA) (A) Max Dynamic Breakover Voltage @ 100/µs (V) Max Single Impulse Discharge Current 10/350µs5,2 (kA) SL1024A090 90 70-120 600 10 10 20 2.5 SL1024A145 145 116-174 500 10 10 20 2.5 SL1024A150 150 120-180 500 10 10 20 2.5 SL1024A230 230 184-276 350 10 10 20 2.5 SL1024A250 250 200-300 400 10 10 20 2.5 SL1024A260 260 210-310 420 10 10 20 2.5 SL1024A300 300 240-360 450 10 10 20 2.5 SL1024A350 350 280-420 500 10 10 20 2.5 SL1024A400 400 320-480 600 10 10 20 2.5 SL1024A420 420 345-500 650 10 10 20 2.5 SL1024A450 450 360-540 650 10 10 20 2.5 SL1024A500 500 400-500 700 10 10 20 2.5 SL1024A600 600 480-720 850 10 10 20 2.5 (1) Total current through center (ground) electrode, both line electrodes pulsed simultaneously; half value through each respective line terminal.
