【产品】新SIDACtor保护晶闸管,让SLIC接口抵抗雷击
——含有符合ITU建议的快速切换电撬结构
LITTELFUSE公司推出了两个SIDACtor保护晶闸管系列,旨在保护SLIC(用户线路接口电路)接口免受雷击感应浪涌和电源故障的损坏。 用于可编程跟踪保护的表面安装型B61089QDR和B9110DF系列晶闸管含有快速切换电撬结构,该结构符合国际电信联盟(ITU)ITU K.20、K.21和K.45建议中基本级别的要求。
SIDACtor B61089QDR和B9110DF系列保护晶闸管产品
B61089QDR双端口Battrax可为仅执行负电压振铃的SLIC卡提供浪涌保护。 B9110DF系列可为执行正电压和负电压振铃的SLIC卡提供浪涌保护,正电压和负电压振铃被用于当今的多数电信应用中。 它还能追踪SLIC芯片组的参考Vcc,当它进入低静态阶段,保护阈值将与这一较低阈值相匹配。
B61089QDR和B9110DF系列的应用包括对下列应用的保护:
• 无线本地环路(WLL)系统
• 需要再生POTS(普通老式电话服务)信号的语音应用
• 网络电话(VoIP)应用
• 专用小交换机(PBX)系统
• 外部交换站(FXS)应用
• 数字对增容系统(DPG)
• 数字环路载波(DLC)系统
• 小型家庭办公室(SOHO)系统
“相比传统的箝制装置,B61089QDR和B9110DF系列可提供更加优越的电撬电源故障保护。”Littelfuse SIDACtor保护晶闸管产品系列总监Jeff Chin表示,“它们将出色的浪涌保护性能与较低的开关阈值和通态电压相结合,确保发挥更强大的保护功效。”
B61089QDR和B9110DF系列SIDACtor保护晶闸管具备下列关键优点:
1)为采用+VBAT和-VBAT基准(B9110DF系列)和-VBAT基准(B61089QDR系列)以及不断变化的VBAT基准的SLIC提供高性能保护。
2)防止在额定范围内发生多次浪涌事件后出现组件性能下降,从而延长了设备使用寿命。
3)帮助线驱动器达到全球各项标准的要求,因为这些设备经过认证、绿色环保并且适合在全球范围内使用。
