【应用】基于国产GDT和TVS设计的DC24V电源防护设计方案,有效提高电源模块的可靠性等级
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
图:DC24V电源防护方案电路图
GDT【UN1812-230CSMD】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。
TVS【SMCJ36CA】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

【选型】国产TVS瞬态抑制二极管用于POE摄像头保护电路设计,ESD等级±15kV,峰值脉冲功率1500W
针对摄像头POE交换芯片的ESD防护应用,推荐国产硕凯电子的TVS瞬态抑制二极管SMCJ51CA,双向防护,工作电压51V,最小击穿电压56.7V,反向漏电流5μA,峰值脉冲功率1500W,ESD防护等级满足IEC61000-4-2标准。
【应用】千兆以太网口设计电路防护方案,采用GDT在变压器前端做共模(八线)浪涌防护
随着千兆以太网口应用范围的逐步扩大,其防护需求也越来越受重视,硕凯电子作为专业的电路保护专家,就经常碰到以太网口防护的客户需求。今天硕凯小编本着好多东西大家一起分享的原则,来给大家介绍硕凯FAE工程师们是如何给千兆以太网口进行防护方案。
基于硕凯TVS SMBJ24CA的车载LED电源静电整改案例分析
本文介绍车载LED电源静电整改分析。对于弱电产品有金属外壳的产品最好是把外壳接到PCB的工作地,或者PCB有大地的外壳接到PCB的大地。对于主IC不能承受很大的工作电压时选用TVS尽量选用钳位电压低的,比如SMBJ24CA。
【应用】全业电子推出DC 24V电源防护方案,满足球机电源、枪机电源等高浪涌防护电源需求
高浪涌防护电源成为行业趋势下,全业电子推出基于GDT陶瓷气体放电管UN1812-230CSMD和UN2E5-230LSMD、以及TVS瞬态抑制二极管SMCJ36CA的DC 24V电源防护方案,满足多种浪涌测试标准。
