国产气体放电管pin-pin替代Brightking（君耀）2RL150M-6，放电响应时间更快，封装更小

时间： 2019-05-12 来源：SC2E5-150LSMD

为防止电信通讯设备（如：电话机、移动电话、调制解调器、传真机、数据通信设备等）因裸露在室外的线路直接遭受雷击或感应雷击浪涌电流导致电信通讯设备内敏感电子器件被打死或烧毁，一般需要加气体放电管做一级防雷保护设计，不过因供货周期和价格压力，很多客户会选择一款低成本、供货周期好的替代方案，本文重点推荐国产硕凯电子的SC2E5-150LSMD可pin-pin替代BRIGHTKING（君耀）公司2RL150M-6 ，典型电性参数对比参考如下图1所示。

通过如上图示易知：

国产硕凯电子气体放电管SC2E5-150LSMD相比BRIGHTKING（君耀）2RL150M-6具有明显的竞争优势：

1、具有650V更低的最大脉冲击穿电压，放电响应时间更快，对故障电压安全保护能力更强。

2、 具有更小的封装体积（5.0mm x 5.0mm x 4.2mm），方形放置牢固，更容易上锡。

硕凯电子气体放电管SC2E5-150LSMD与BRIGHTKING（君耀）2RL150M-6两者的封装尺寸示意图，参考如下图2所示。
