瞬态抑制二极管的选型
1、确定被保护电路的最大直流或连续工作电压、电路的额定标准电压和“高端”容限。
2、TVS额定反向关断VWM应大于或等于被保护电路的最大工作电压。
若选用的VWM太低,器件可
能进入雪崩或因反向漏电流太大影响电路的正常工作。
串行连接分电压,并行连接分电流。
3、TVS的最大箝位电压VC应小于被保护电路的损坏电压。
4、在规定的脉冲持续时间内,TVS的最大峰值脉冲功耗PM必须大于被保护电路内可能出现的峰值脉
冲功率。
在确定最大箝位电压后,其峰值脉冲电流应大于瞬态浪涌电流。
5、对于数据接口电路的保护,还必须注意选取具有合适电容C的TVS器件。
6、根据用途选用TVS的极性及封装结构。
交流电路选用双极性TVS较为合理;多线保护选用TVS阵
列更为有利。
7、温度考虑。
瞬态电压抑制器可以在-55~+150℃之间工作。
如果需要TVS在一个变化的温度工作,
由于其反向漏电流ID是随增加而增大;功耗随TVS结温增加而下降,从+25℃到+175℃,大约线性下降50%雨击穿电压VBR随温度的增加按一定的系数增加。
因此,必须查阅有关产品资料,考虑温度变化对其特性的影响。

双向瞬态抑制TVS二极管型号大全
双向瞬态抑制TVS⼆极管型号⼤全过电压防浪涌保护器件TVS瞬态电压抑制⼆极管,是⼀种⾼效新型的电路保护元件,凭借其⾃⾝独有的优势:半导体⼯艺、稳定可靠、玻璃钝化⼯艺、导通电压精准、PS秒级响应速度、瞬态功率⼤、击穿电压偏差⼩、低漏电流、低动态内阻、箝位电压易控制、封装形式多样、⼩体积易安装等等,被⼴泛应⽤于敏感电⼦产品中,如汽车电⼦、⼯业设备、通讯设备、消防电⼦、家电等等。
TVS⼆极管种类很多,根据⽅向可分为单向TVS和双向TVS;根据极性可分为单极性TVS和双极性TVS;根据外形可分为贴⽚TVS和直插TVS;根据功率可分为⼤功率TVS和⼩功率TVS……接下来,TVS⼆极管⼚家东沃电⼦DOWOSEMI重点要分享的是有关双向TVS⼆极管的话题。
双向TVS⼆极管和单向TVS有什么区别呢?如何区分双向TVS⼆极管?双向TVS⼆极管型号有哪些?双向TVS⼆极管和单向TVS⼆极管的区别单向和双向TVS管伏安特性曲线和相关参数说明如下图:从上图可以看出,双向TVS⼆极管伏安特性曲线在第⼀象限与第三象限极性相反,特性相似、当单向TVS⼆极管反向偏置时,它有两种⼯作模式:待机(⾼阻抗)或钳制(相对的低阻抗),详见单向TVS⼆极管伏安特性曲线第三象限。
在应⽤⽅⾯的区别,⼀般⽽⾔,单向TVS应⽤在直流电路中,双向TVS应⽤在交流电路中,具体详情建议咨询专业的技术员。
如何区分双向TVS⼆极管?双向:bi-directional unit,简称Bi;单向:uni-directional unit,简称Uni。
关于TVS⼆极管如何区分单双向这个问题,最可靠的⽅法就是查看对应料号的产品⼿册,其中Bi列表中表⽰的是单向,Uni列表中表⽰的是双向。
当然还可以根据型号更直观地辨别,TVS⼆极管型号尾缀CA是双向,A的话是单向,如3KP33CA是双向TVS⼆极管,3KP33A是单向TVS。
当然,不同品牌供应商对TVS⼆极管型号命名⽅式还是略有差异的,⼀般⽽⾔,都是国标统⼀的型号,不会存在太⼤的差异。

TVS(瞬变抑制)二极管参数与选型
TVS(瞬变抑制)二极管参数与选型TVS管的英文名是TRANSIENT VOLTAGE SUPPRESSOR,中文名叫瞬变抑制二极管。
它在承受瞬间高能量脉冲时,能在极短的内由原来的高阻抗状态变为低阻抗,并把电压箝制到特定的水平,从而有效的保护用户的设备和元器件不受损坏。
由于其具有箝位电压低、动作时间快等特点;因此比较适合于多级保护电路的末级保护。
此外也能和其它保护元件配合使用,组成专用的防雷装置。
目录TVS的参数特性TVS的应用TVS和其它浪涌保护元件的区别TVS的选用方法TVS管TVS的参数特性1.TVS特性TVS管是典型的PN结雪崩器件,和普通稳压管的击穿特性差不多。
但这条曲线只反映了TVS特性的一个部分,还必须补充下图所示的特性曲线,才能反映TVS的全部特性。
这是在双踪示波器上观察到的TVS管承受大电流冲击时的电流及电压波形。
图中曲线1是TVS管中的电流波形,它表示流过TVS管的电流由1mA突然上升到峰值,然后按指数规律下降,造成这种电流冲击的原因可能是雷击、过压等。
曲线2是TVS管两端电压的波形,它表示TVS中的电流突然上升时,TVS两端电压也随之上升,但最大只上升到VC值,这个值比击穿电压VBR略大,从而对后面的电路元件起到保护作用。
TVS在电路中和稳压管一样,是反向使用的。
2.参数说明A.击穿电压(VBR):TVS在此时阻抗骤然降低,处于雪崩击穿状态。
B.测试电流(IT):TVS的击穿电压VBR在此电流下测量而得。
一般情况下IT取1mA。
C.反向变位电压(VRWM):TVS的最大额定直流工作电压,当TVS两端电压继续上升,TVS将处于高阻状态。
此参数也可被认为是所保护电路的工作电压。
D.最大反向漏电流(IR):在工作电压下测得的流过TVS的最大电流。
E.最大峰值脉冲电流(IPP):TVS允许流过的最大浪涌电流,它反映了TVS的浪涌抑制能力。
F.最大箝位电压(VC):当TVS管承受瞬态高能量冲击时,管子中流过大电流,峰值为IPP,端电压由VRWM值上升到VC值就不再上升了,从而实现了保护作用。
贴片封装TVS瞬变管5.0SMDJ33CA说明
贴片封装TVS瞬变管5.0SMDJ33CA说明硕凯电子(Sylvia)一、产品概述TVS瞬变管(Transient Voltage Suppressor)的电气特性是由P-N结面积、掺杂浓度及晶片阻质决定的。
其耐突波电流的能力与其P-N结面积成正比。
TVS广泛应用于半导体及敏感器件的保护,通常用于二级电源和信号电路的保护,以及防静电等。
其特点为反应速度快(为ps级),体积小,脉冲功率较大,箝位电压低等。
其10/1000μs波脉冲功率从400W~30KW,脉冲峰值电流从0.52A~544A;击穿电压有从6.8V~550V的系列值,便于各种不同电压的电路使用。
二、双向I-V曲线特性三、产品特性1、为表面安装应用优化电路板空间2、低泄漏3、双向单元4、玻璃钝化结5、低电感6、优良的钳位能力7、5000W的峰值功率能力在10×1000μ波形重复率(占空比):0.01%8、快速响应时间:从0伏特到最小击穿电压通常小于1.0ps9、典型的,在电压高于25V时,反向漏电流小于5μA10、高温焊接:终端260°C/40秒11、典型的最大温度系数△Vbr=0.1%x Vbr@25°C x△T12、塑料包装有保险商实验室可燃性94V-013、无铅镀雾锡14、无卤化,符合RoHS15、典型失效模式是在指定的电压或电流下出现16、晶须测试是基于JEDEC JESD201A每个表4a及4c进行的17、IEC-61000-4-2ESD15kV(空气),8kV(接触)18、数据线的ESD保护符合IEC61000-4-2(IEC801-2)19、数据线的EFT保护符合IEC61000-4-4(IEC801-4)四、型号标识五、选型与应用①TVS管使用时,一般并联在被保护电路上。
为了限制流过TVS管的电流不超过管子允许通过的峰值电流IPP,应在线路上串联限流元件,如电阻、自恢复保险丝、电感等。
②击穿电压VBR的选择:TVS管的击穿电压应根据线路最高工作电压UM按公式:VBRmin ≥1.2UM或VRWM≥1.1UM选择。

TVS瞬态电压抑制二极管(钳位二极管)原理参数
瞬态电压抑制二极管(TVS)又叫钳位二极管,是目前国际上普遍使用的一种高效能电路保护器件,它的外型与普通二极管相同,但却能吸收高达数千瓦的浪涌功率,它的主要特点是在反向应用条件下,当承受一个高能量的大脉冲时,其工作阻抗立即降至极低的导通值,从而允许大电流通过,同时把电压钳制在预定水平,其响应时间仅为10-12毫秒,因此可有效地保护电子线路中的精密元器件。
瞬态电压抑制二极管允许的正向浪涌电流在TA=250C,T=10ms条件下,可达50~200A。
双向TVS可在正反两个方向吸收瞬时大脉冲功率,并把电压钳制到预定水平,双向TVS适用于交流电路,单向TVS一般用于直流电路。
可用于防雷击、防过电压、抗干扰、吸收浪涌功率等,是一种理想的保护器件。
耐受能力用瓦特(W)表示。
瞬态电压抑制二极管的主要电参数(1)击穿电压V(BR)器件在发生击穿的区域内,在规定的试验电流I(BR)下,测得器件两端的电压称为击穿电压,在此区域内,二极管成为低阻抗的通路。
(2)最大反向脉冲峰值电流IPP在反向工作时,在规定的脉冲条件下,器件允许通过的最大脉冲峰值电流。
IPP与最大钳位电压VC(MAX)的乘积,就是瞬态脉冲功率的最大值。
使用时应正确选取TVS,使额定瞬态脉冲功率PPR大于被保护器件或线路可能出现的最大瞬态浪涌功率。
瞬态电压抑制二极管的分类瞬态电压抑制二极管可以按极性分为单极性和双极性两种,按用途可分为各种电路都适用的通用型器件和特殊电路适用的专用型器件。
如:各种交流电压保护器、4~200mA电流环保器、数据线保护器、同轴电缆保护器、电话机保护器等。
若按封装及内部结构可分为:轴向引线二极管、双列直插TVS阵列(适用多线保护)、贴片式、组件式和大功率模块式等。
瞬态电压抑制二极管的应用目前已广泛应用于计算机系统、通讯设备、交/ 直流电源、汽车、电子镇流器、家用电器、仪器仪表(电度表)、RS232/422/423/485、I/O、LAN、ISDN 、ADSL、USB、MP3、PDAS、GPS、CDMA、GSM、数字照相机的保护、共模/差模保护、RF耦合/IC驱动接收保护、电机电磁波干扰抑制、声频/视频输入、传感器/变速器、工控回路、继电器、接触器噪音的抑制等各个领域。
