优恩半导体ESD静电保护器件等产品，可进行电力线网络通讯端口保护

时间： 2021-10-12 来源：优恩半导体

技术问答

电力线网络通讯端口（POE），它是一种网络通讯与供电系统相集成的一种新型网络传输技术，即POE技术。它能在确保现有结构化布线安全的同时又保证现有网络的正常运作，大大简化了布线和施工的难度，最大限度地降低投入成本，完整的POE系统包括供电端设备（PSE）和受电端设备（PD）两大部分。推荐优恩半导体的几款产品可进行POE端口保护。

应用前景：

● 强对流等极端现象造成的雷雨天气，易使POE端口产生损坏

● POE端口同时存在电源与数字信号，增大了防护难度

● 防护不到位可能导致负载产品的使用寿命缩短，将增大维修成本

应用领域：

● POE供电

● POE分离器

● POE交换机

● POE连接器

● AP等

防护电路图：

产品外观：

产品规格：

产品外观：

ESD03V32D-LC UN3E5-470LSMD SMCJ58CA 14D820K

产品规格：

产品说明及注意事项：

● 此方案此采用GDT与MOV的串联在变压器的前段做八线共模保护

● 变压器后段则用TVS\ESD做次级差模保护，吸收差模能量兼顾静电防护

● 前端电源则通过电感L传输，在电感两端的残压通过TVS管吸收

● 此方案满足IEC610000-4-5中8\20us的浪涌测试

● 同时满足IEC610000-4-2的静电测试
