AMAZING晶炎科技在*近IPC主晶片的參考設(shè)計(jì)上，Ethernet端口的傳輸速度已由1Gbps升級(jí)至2.5Gbps，各工業(yè)電腦大廠在研發(fā)新項(xiàng)目時(shí)，也開(kāi)始以Ethernet 2.5Gbps作為標(biāo)準(zhǔn)設(shè)計(jì)，在測(cè)試ESD或是Surge時(shí)，相對(duì)也較常因2.5Gbps晶片對(duì)ESD/Surge較為敏感而遇到測(cè)試無(wú)法通過(guò)的問(wèn)題，本文將介紹Ethernet 2.5Gbps的ESD/Surge完整防護(hù)對(duì)策。晶炎科技Differential mode的Surge防護(hù)元件除了前述AZ5B0S-01F之外，亦有推出DFN1006P2E(0402)封裝的防護(hù)元件AZ522S-01F，寄生電容為0.2pF(Typ.)，可抗受IEC61000-4-5 Surge (8/20μs) 6.5A的能量。在Surge(8/20μs) 6.5A時(shí)的Surge clamping voltage約為5V. AZ522S-01F的Surge clamping voltage I-V特性曲線。AMAZING晶炎科技除了Common mode(線對(duì)地)以及Differential mode(線對(duì)線)的防護(hù)元件，在系統(tǒng)進(jìn)行ESD及Surge的測(cè)試時(shí)，亦時(shí)常見(jiàn)到能量耦合至LED控制訊號(hào)，而導(dǎo)致LAN PHY損壞的問(wèn)題。故在LAN LED控制訊號(hào)線的防護(hù)也相對(duì)的重要，建議可先預(yù)留防護(hù)元件在LED的控制訊號(hào)線上，2.5Gbps Ethernet 的完整保護(hù)線路.
