气体放电管,微型管等离子气体过压保护器,微型管等离子GDT,SL0902A 气体放电管,微型管等离子气体过压保护器,微型管等离子GDT,SL0902A 气体放电管,微型管等离子气体过压保护器,微型管等离子GDT,SL0902A 气体放电管,微型管等离子气体过压保护器,微型管等离子GDT,SL0902A

这些输入端发出的广播信号都以射频波段传输, 它们将各种电视频率进行了扩展,分别是:模拟电视——806 MHz;数字电视——698 MHz ,有线电视——1,000 MHz;卫星传送——2,500 MHz。 由于这些信号具有高频属性,因此必须考虑抑制器的电容量,以避免信号衰减。 这些电气威胁都来自雷电浪涌和ESD。


本文讲述有线电视/卫星电视/ 地面数字电视输入的电路保护。如下图所示,可使用LITTELFUSE推出的气体放电管SL0902A(2.5KA)或SL1002A(5KA)来保护输入信号线路。 具体的器件号应通过将浪涌的峰值脉冲电流值与相应的气体放电管电流值相匹配来确定。由于这种输入易受雷击电涌的损害,其测试条件应参考UL 1449和IEC 61000-4-5等标准。 通常使用的是8x20波形。


PulseGuard® 抑制器的电容量值同样很低,但是不宜用于本输入线路。 PulseGuard器件的功能不够强大,无法提供雷击浪涌保护;这些器件专为ESD保护而设计。


有线电视/卫星电视/ 地面数字电视输入的电路保护电路图


SL0902A气体放电管是一款两端子宽频带优化微型管等离子气体过压保护器(GDT),无铅产品,且符合RoHS标准。根据IEC 61000-4-5的规定,8/20μS脉冲下有2.5KA的浪涌性能,超小型设备,低电容(<1pF),电压范围为90V至600V。专门用于在表面贴装组件应用中为电气和通信设备提供瞬态过电压保护。 此系列采用了非放射性元素,可提供最尖端的保护。


而SL1002A气体放电管专为宽带设备而开发,根据IEC 61000-4-5的规定,8/20µ脉冲下有5kA的浪涌性能。可针对范围为100V/µs至1kV/µs之间的快升瞬态电压而提供高层次保护,该瞬态电压通常因雷击干扰而引起。并且其信号损失几可忽略,只有1.5GHz。 这些器件的功能非常强大,能够转移5000A的脉冲,并且不会造成损害。 针对交流电源的长期交叉,建议使用过电流保护。

【应用】气体放电管、二极管阵列和保护型晶闸管在G.FAST电路保护所面临的挑战

对于G.FAST等高带宽线路,放置在线路上的任何电路保护元件的电容都可能会降低信号强度,从而降低其速率和覆盖范围。但是节点中的G.FAST调制解调器和电路必须受到保护,防止雷电引起的浪涌造成损坏。尽管客户驻地设备(CPE)设计人员可采取三种基本的电路保护方案:Littelfuse均可提供的气体放电管(GDT)、瞬态电压抑制(TVS)二极管阵列和保护型晶闸管。
