【选型】硕凯TVS SMCJ30CA和气体放电管SC3E5-90LSMD为24V电源端口提供浪涌防护方案
客户产品为24V供电，电源端口需通过雷击浪涌测试，一级使用气体放电管，二级用TVS，中间用电感退耦和PPTC，硕凯可以提供浪涌防护方案并且可以为客户进行整改。
常见浪涌防护方案如下：
一级防护使用气体放电管推荐硕凯SC3E5-90LSMD参数如下：
1、直流击穿电压（100V/S）：90V
2、最大脉冲击穿电压（1KV/us）：600V
3、最小绝缘电阻（at 50V）：1GΩ
4、通流量（8/20uS ±5 times）：5KA
5、最大极间电容（1MHz）：1.5pF
二级防护使用TVS使用硕凯SMCJ30CA参数如下：
1． 工作电压30V；
2． 击穿电压33.3V~36.8V；
3． 工作温度-55 to +150°C；
4． 峰值功率1500W；
产品优势：
1. 硕凯90V气体放电管和30V TVS可以满足客户线路防护要求；
2. 硕凯原厂可以提供EMC测试以及相关整改方案；
3. 性价比高，交期短

【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%。
【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。
【选型】国产气体放电管pin-pin替代Brightking（君耀）2RL090M-6，成本至少降10%
为实现低成本高性能pin-pin替代BRIGHTKING（君耀）公司2RL090M-6气体放电管，推荐选用国产硕凯电子的SC2E5-90LSMD，两者电性参数基本一致，不过，国产硕凯电子的气体放电管SC2E5-90LSMD具有650V更低的最大脉冲击穿电压，响应时间更快，产品对的故障安全保护能力更强。同时，具有更小的封装体积（5.0mm x 5.0mm x 4.2mm），方形放置牢固，更容易上锡。

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。

DC24V电源端口浪涌保护
DC24V电源端口浪涌保护DC24V电源是一种为设备提供稳定、可靠的直流电压输出的电源，其广泛应用于工业自动化控制系统。此方案设计为多级保护的方式，初级采用通流能力较强的陶瓷气体放电管和压敏电阻组合来承受泻放大的浪涌电流，中间使用电感做退耦，次级选用响应电压精准、稳定且快速的TVS管做保护，能有效抑制各类浪涌过电压，使后端的DC芯片及电路得到全面的保护。
赛尔特（SETsafe丨SETfuse）高通流型气体放电管选型指南
描述- 气体放电管 Gas Discharge Tube（GDT）是一种单间隙或多间隙的开关型过电压保护器件。在正常情况下，GDT是处于高阻状态；当受到浪涌冲击时，GDT将从高阻抗状态变为低阻抗状态，并将浪涌能量释放到大地，降低电路残压，进而保护设备电路或人身免受瞬态过电压的危害。GDT是在金属电极、金属化陶瓷、惰性气体或与其它混合气体经过高温封接而成。

【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？
【技术】电源端口的防护电路设计用到的3个保护元件
爱浦电子将在本文介绍电源端口的防护电路设计通常用到三大类保护元件：压敏电阻器、气体放电管、瞬态抑制二极管。
