Littelfuse releases the big surging current protection silicon-controlled rectifier
Littelfuse releases the Q2L series C grade SIDACtor device, its area of position occupied is 3.3x3.3mm, the height is only 1mm, it is telecommunications that are protected and offered the rank (under 500A of high surge protection in the market, its rated value reachable 2x10 s of surging) Middle and minimum protection silicon-controlled rectifier. It is application of intensive circuit board that its small-scale QFN capsulates, such as linear card and ideal choice of the other multiple channels telecommunication equipment.
The Q2L series C grade SIDACtor device offers unique obeying the voltage protection of the attitude bidirectionally, and offer Ipp rated value of the wide-range: 5x310/10x700? 200A (ITU/YDT waveform) under s condition , 10x1000? 100A (GR 1089 waveform) under s condition , 10x560? 150A (TIA-968-A) under s condition .
On the basis of the designs of Teccor brand SIDACtor technology and innovation that is proved, the C grade chip is unique. This unique device has disposed lead wire on the chip bottom, satisfiable drain of UL/EN 60950 and demand apt to wash, have realized more high-efficient ground PCB routing. Because is apt to wash, this device can locate in PCB to recite the end, thus the saving in space, and further reduced the magnitude of the circuit board.
The additional advantage of C grade SIDACtor is extremely durable, in the apt application exposed to the environment, for instance the remote terminal, loop extender, wireless remote station, transponder have remarkable characteristics while standing etc..
The Q2L series C grade SIDACtor device accords with RoHS order, recognizable UL, its surging accords with ability and keeps the same with demand for GR-1089-CORE. At the same time device too and CORE first grade GR 1089, second thunder and lightning is assaulted, ITU K.20/K.21 foundation or enhanced thunder and lightning is assaulted, UL/EN 60950 pulse testing environment, YD/T 993-1998 and IEC 61000-4-5 are compatible. Special, when using with TeleLink thermal link, it can realize more high compatibility and not need extra series resistor, and the design efficiency that so can optimize reduces the additional cost.
