SL1122A Datasheet | Littelfuse

features a high performance Alpha Gas Plasma Tube in conjunction with a high speed Silicon Avalanche Diode ( SAD ). These devices are matched so that High speed pulses are initially clamped by the SAD, then as the current rises, the transient energy is switched through the Gas Tube. The Hybrid offers high levels of performance on fast rising transients in the domain of 100V/µS to 10 KV/µS, so eliminates the dv/dt switching delay normally exhibited by standard GDT’s. These devices are extremely robust and are able to divert a 10,000Amp pulse without destruction, so are ideal for central office ( telephone exchange ) protection. FEATURES - Ro Hs pliant - Excellent response to fast rising transients. - Flat response up to 10KV/µS. - 10KA surge capability tested with 8/20µS pulse as defined by IEC 61000-4-5 - SAD ensures short circuit failure mode in the event of severe GAS DISCHARGE TUBES transient overload. - Thermal failsafe. Applications: - MDF protection - Alarm panels. - ADSL equipment. - XDSL equipment. - General Tele Equipment a b e 3 ELECTRODE GDT a=TIP b=RING e=GROUND (centre electrode) GRAPHICAL SYMBOL All dimensions in mm Mechanical Specifications: ORDERING INFORMATION SL 1122 A Voltage Weight: Materials: Device Marking: 2.7g (0.095 oz.)
