时间： 2021-04-25 来源：优恩半导体

技术问答

方案描述：

DC12V电源广泛使用在LED、安防等电源行业，远距离户外传输，导致设备及易遭受雷击浪涌及过压等损坏，此方案前端采用大通流放电管泄放雷击、浪涌大电流，后级采用精准、稳定、快速的TVS管保护，使后端的电路得到全面的防护。

解决方案内容：

1颗 UN Semiconductor 瞬态抑制二极管：SMCJ18CA

1颗 UN Semiconductor 自恢复保险丝：UN30-XXX

1颗 UN Semiconductor 陶瓷气体放电管：UN1812-90CSMD

符合要求：

IEC 61000-4-2 ESD

IEC 61000-4-5 Surge

替代选项：

其他解决方案：

DC24V-浪涌防护&静电放电，其他UN Semiconductor解决产品SMBJ18CA、UN2E5-90LSMD、14D220K

优点：

此方案使用较小体积的陶瓷气体放电管，节约单板空间的同时又避免使用压敏电阻时出现的一些安全隐患，用最小的体积做到最合理的防护。

以上方案仅供参考，如欲了解更多详情可咨询世强技术专家。
