【应用】TVS管UNS1K58CA用于POE-电源口静电放电及雷击浪涌过压防护，有效保护电路及节省PCB空间

时间： 2022-05-29 来源：优恩半导体

技术问答

POE-电源是一种在线供电技术，对功率较小且支持POE受电的设备都可以提供，尤其对无线AP来说，直接省去了变压器，通过一根网线就能搞定供电和数据传输。

针对POE-电源口静电放电及雷击浪涌过压防护，小编推荐使用TVS管 UNS1K58CA产品型号，或搭配GDT陶瓷气体放电管UN2E5-90LSMD一起使用。

【技术】浅析瞬态抑制二极管（双向TVS管）

TVS管也叫瞬态抑制二极管，TVS管是吸收浪涌功率用的，能在极短时间内承受反向电压冲击，使两极间的电压钳位于一个特定电压上，避免后面的电路受到冲击。简单的说就是做过压保护的，在通信等产品中很常见。连接时必须反向工作在电路电源、地两端，与稳压二极管类似，但不需要限流电阻。

【经验】如何判断贴片TVS管的单双向及正负极？

TVS管按电性，有单向，双向之分，单向管只能保护一个面，双向可以两边保护。TVS管一般应用在电子电路中，有贴片式TVS管以及轴向引线型TVS管，常用贴片TVS管型号有：SOD123、DO-214AC/SMA、DO-214AA/SMB、DO-214AB/SMC、DO-218AB；引线型TVS管有：DO-201AL/DO-41、DO-204AC/DO-15、DO-201、P600等。
