电源是电子产品中的重要模块,它是电子设备运行的能量来源,电源模块失效直接就可能导致电子设备的瘫痪,造成不可挽回的损失。 因此各大厂家在生产电子设备时,尤其重视电源模块的可靠性。电子元件的可靠性是电子设备可靠性的基础,要提高设备或系统的可靠性必须提高电子元件的可靠性。硕凯电子提出了在电路保护领域层面的防护设计——DC24V电源防护方案,以帮助提高电源模块的可靠性等级。


一、应用背景

1.全球气候变暖,雷雨天气增多

2.电源雷击损坏后,危害大

3.电源雷击损坏后,维修成本高

4.高浪涌防护设备成为行业趋势


二、防护方案与硕凯器件

陶瓷气体放电管

GDTUN1812-230CSMD】直流标称电压:230±20%V,冲击电流(8/20μS):2kA,电容值<1.0pF,电阻值>1GΩ;

GDT【UN2E5-230LSMD】直流标称电压:230±20%V,冲击电流(8/20μS):5kA,电容值<1.0pF,电阻值>1GΩ。


瞬态抑制二极管

TVSSMCJ36CA】Vbr:40.0-44.2V;Ir:5μA;Vrwm:36.0V,Ipp:25.8A;Vc  :58.1V;封装:SMC/DO-214AB


三、方案应用

1.球机电源

2.枪机电源

3.电源适配器

4.LED电源

5.家庭音乐播放器

6.数码相框电源

7.车载电源

8.其他DC24V供电电源


四、方案说明与注意事项

1.此方案后级采用反应时间很快、残压较低的TVS管

2.前级采用通流量大、体积小、无续流能力的贴片GDT

3.中间用电感L1、L2做退耦,驱动GDT泄放大电流

4.此电源方案满足IEC61000-4-5、GBT17626.5等浪涌测试标准

5.此电源方案可通过1.2/ 50-8/20μS组合波浪涌测试
