【应用】硕凯电子SMBJ24CA表面贴装TVS在汽车氛围灯的应用
汽车氛围灯是一种能够起到装饰作用的照明灯具，可根据车辆状态、环境以及个人喜好来改变其亮度和颜色，可以提高车内人员的乘车体验，和汽车品牌辨识度。在夜间行驶时，内饰氛围灯可降低视觉疲劳，在一定程度上提高驾驶员的行车安全性。随着汽车电子技术的发展，用户对产品的可靠性、体积和成本要求越来越高， 在此类产品的组成中，防护电路是必不可少的一部分。
硕凯设计的电源防护方案是基于SMBJ24CA。SMBJ24CA通过AECQ-101汽车级认证，小尺寸贴片型封装（SMB），可优化电路板，反应速度快（＜1PS），精准的钳位电压更好的保护到后级线路。该防护方案可以满足国标ISO7637-2 Pulse 1-4测试，硕凯推荐的电源防护方案图如下：
SMBJ24CA表面贴装TVS的特点：
峰值耗散功率：600W
可承受最大反向电压：24V
反向漏电流小：＜5uA
小体积封装：SMB/DO-214AA
反应速度快：＜1ps
钳位电压精准

【应用】TVS SR05-4B用于SIM卡防护，可通过5A浪涌电流有效进行保护
由于SIM卡容易被接触，尤其是集成度很高的板子上，一定要加防护器件，否则很容易耦合进静电。硕凯电子的TVS SR05-4B的结电容非常小，在0.5pF到1pF之间，所以不会影响通信，而且SR05-4B的最大通流量是可以通过5A的浪涌电流，远高于普通的ESD（静电防护器件），对静电有更好的泄放通路。
【应用】国产TVS SMAJ5.0A用于气体报警器MCU通讯端口，ESD等级达±15kV，工作电压5V
气体报警器需要增加ESD防护器件。推荐国产硕凯电子的TVS SMAJ5.0A，工作电压5V，峰值脉冲功功率400W，ESD防护等级满足±15kV（空气放电）/±8kV（接触放电），小尺寸封装，是气体报警器MCU通讯端口保护电路的优秀选择。
【应用】基于国产SOT-143封装TVS的USB2.0防护方案
USB2.0的芯片集成度高，易受静电损坏。基于硕凯电子的TVS设计的USB2.0防护方案，在USB2.0的电源线、数据线用1颗TVS对地做防护，钳位静电电压。所用TVS的结电容小于1.2pF，在USB2.0最高速率480Mbps时都可以完整传输信号。

硕凯电子SM2KBF系列TVS参数详解及防护应用
硕凯电子推出的SM2KBF系列TVS是专用于低压直流电源的浪涌防护器件， 该器件采用的是SMBF小封装，相对同封装体积的普通系列TVS功率大能做到更大，双向无极性区分，综合防护能力要比同体积产品高得多，可有效降低设计成本。
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。
【视频】硕凯TVS管SMA至DO-218AB封装适配7637车载浪涌5A和5B全套解决方案|世强硬创新产品在线研讨会
在世强硬创新产品在线研讨会——国产汽车电子专场中，硕凯电子技术专家为我们做了演讲。传统TVS现已不能满足大部分客户的需求，为了满足更高了ISO7637-2的测试等级，硕凯特推出7637车载浪涌5A和5B全套解决方案，封装更全面，体积更小巧，性能更稳定，方案更成熟，能解决各种车载浪涌场合的实际防护问题，可以提高客户产品的使用寿命和防护等级！
单向TVS和双向TVS有什么区别？
单向TVS管的正向特性与普通稳压二极管相同，反向击为典型的PN结雪崩，双向TVS管的V-I特性曲线是两只单向TVS“背靠背”组合，其正反两个方向都具有相同的雪崩击穿特性和箝位特性。推荐硕凯（SOCAY）的单向TVS和双向TVS，响应速度为<1ps级，击穿电压有从6.8V～550V， 钳制电压比较准确,误差±5%;具体见选型手册： https://www.sekorm.com/doc/1173258.html
硕凯电子TPSMEJ24CA车规级TVS专用于汽车中，击穿电压26.7~29.5V，功率5000W
每当我们打开车门的时候，产品LED灯会亮，迎宾灯夜间开门十分耀眼，看的见路况，安全时尚。但是在汽车中由于电源和负载断开时或电流突然中断等瞬态现象层出不穷，所以真正要适用在汽车上还要通过ISO7637-2标准，该标准规定了各种瞬态现象的波形和电压等级。硕凯电子研发的TPSMEJ24CA就是专门用在汽车上的车规级TVS。
