【应用】基于硕凯电子国产GDT、PTC和TVS设计的汽车CAN总线防护方案
CAN是控制器局域网络(Controller Area Network)的简称,CAN总线传输距离较远,易受电磁环境干扰。本文将介绍基于硕凯电子的GDT、PTC和TVS设计的汽车CAN总线防护方案。
一、防护电路图
二、应用背景
1、雷雨天气增多
2、CAN总线传输距离较远
3、CAN传输速率最高可达1Mbps
4、易受电磁环境干扰
三、方案应用
1、汽车电子
2、通信设备
四、方案说明及注意事项
1、前端采用通流量大的GDT,泄放大电流
2、后级采用反应时间快的TVS,残压低,有效保护CAN控制芯片
3、中间采用PTC做退藕,让前端GDT更容易动作,达到泄放电流作用
4、本方案满足IEC61000-4-2、GBT1762.2等静电标准,IEC61000-4-5、GBT1762.5等浪涌标准
5、本方案在差模、共模均采用的是同型号的TVS和GDT,防护无死角
6、可通过10/700μS(等效内阻40ohm)、1.2/50-8/20μS测试,具体防护等级需参考GDT和TVS的通流量

【应用】国产气体放电管UN1812-90CSMD在百兆以太网防雷方案中的应用
网络设备遭受雷击损坏后,不仅会带来较大危害,还增加了其维修成本,设计相关的防雷保护十分重要。本文讲述硕凯电子器件设计的百兆以太网防雷方案,分别推荐了UN1812-90CSMD和ESD03V32D-LC,该方案满足国际标准IEC61000-4-5( 10/700μs )第四级。
【选型】防雷保护电路中气体放电管4532-091-LF的备选方案,国产GDT气体放电管实际放电电流达3KA
在防雷保护电路中,气体放电管GDT通常应用于第一级,起泄放雷电暂态过电流和限制过电压作用。市场上有很多客户选用君耀电子的气体放电管4532-091-LF,不过因供货周期和价格压力,很多客户会选择一款低成本、供货周期好的替代方案,本文重点推荐硕凯电子的SC1812-90CSMD可完美替代4532-091-LF,同时体积更小,成本降低10%。
【产品】国产三极方形陶瓷气体放电管SC3E8-230HSMD,具有≤1.5pF的寄生电容值,适合高浪涌的防护
硕凯电子推出了一款三极方形陶瓷气体放电管(GDT),型号SC3E8-230HSMD,尺寸为10mm×8mm×7.9mm,该型号具有≤1.5pF的寄生电容值和25KA的高浪涌承受能力,使得其非常适合高浪涌的防护应用。
【选型】如何为车载12V电源/24V电源端口过压保护选择一款合适的TVS保护器件?
为满足车载电源符合JASO高耐压测试标准,通常在直流电源输入端加入一款双向TVS管做过压防护设计,推荐硕凯的双向TVS管TPSMBJ22CA,TPSMBJ24CA,TPSMBJ33CA,TPSMBJ36CA,可以满足设计需求。
【经验】直流电源端口防雷电路退耦器件该怎么选?
在日常直流电源端口防雷电路设计时,一般遵循“多级防护,逐级消减”的原则,但由于采用不同的防护器件,其击穿电压、响应时间等参数不同,因此电路中通常需要增加退耦器件。本文将结合国产硕凯电子的防护器件讨论直流电源端口防雷电路退耦器件该怎么选?
【应用】国产瞬态抑制二极管SMBJ15CA用于太阳能监控系统,采用SMB封装,规格为15V/600W
太阳能无线监控系统主要由太阳能供电系统、无线视频传输系统、视频监控系统三个子系统组成。硕凯电子在太阳能监控器防护方面已有丰富的经验,广泛使用SMBJ15CA用于视频监控系统12V供电线路。SMBJ15CA断态电压为15V,额定功率为600W。
