瞬态电压抑制二极管(TVS)特点及主要参数

瞬态电压抑制二极管(TVS)特点及主要参数一、TVS器件的特点瞬态（瞬变）电压抑制二级管简称TVS器件，在规定的反向应用条件下，当承受一个高能量的瞬时过压脉冲时，其工作阻抗能立即降至很低的导通值，允许大电流通过，并将电压箝制到预定水平，从而有效地保护电子线路中的精密元器件免受损坏。

TVS能承受的瞬时脉冲功率可达上千瓦，其箝位响应时间仅为1ps（10-12S）。

TVS允许的正向浪涌电流在T ＝25℃，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，并把电压箝制到预定水平，双向TVS适用于交流电路，单向TVS一般用于直流电路。

二、TVS器件的电特性1、单向TVS的V-I特性如图1-1所示，单向TVS的正向特性与普通稳压二极管相同，反向击穿拐点近似“直角”为硬击穿，为典型的PN结雪崩器件。

从击穿点到Vc值所对应的曲线段表明，当有瞬时过压脉冲时，器件的电流急骤增加而反向电压则上升到箝位电压值，并保持在这一水平上。

2、双向TVS的V-I特性如图1-2所示，双向TVS的V-I特性曲线如同两只单向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，正反两面击穿电压的对称关系为：0.9≤V(BR)(正) /V（BR）(反) ≤1.1，一旦加在它两端的干扰电压超过箝位电压Vc就会立刻被抑制掉，双向TVS在交流回路应用十分方便。

三、TVS器件的主要电参数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I PP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。

I PP与最大箝位电压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P PR大于被保护器件或线路可能出现的最大瞬态浪涌功率。

TVS二极管参数简介及应用

TVS瞬变二极管（瞬态电压抑制器）主要特性参数和选用注意事项瞬变二极管是一种二极管形式的高效能保护器件，具有极快的响应时间和相当高的浪涌吸收能力。

当TVS二极管的两端受到反向瞬态过压脉冲时，能以极高的速度把两端间的高阻抗变为低阻抗，以吸收瞬间大电流，并将电压箝制在预定数值，从而有效保护电路中的元器件免受损坏。

本文讲述了TVS器件的主要特性参数和选用注意事项，同时给出了TVS在电路设计中的应用方法。

1 TVS二极管的特性及主要参数1.1 TVS二极管的器件特性在规定的反向应用条件下，TVS二极管对受保护的线路呈高阻抗状态。

当瞬间电压超过其击穿电压时，TVS二极管就会提供一个低阻抗的路径，并通过大电流方式使流向被保护元器件的瞬间电流分流到TVS二极管，同时将受保护元器件两端的电压限制在TVS 的箝制电压。

当过压条件消失后，TVS二极管又恢复到高阻抗状态。

与陶瓷电容相比，TV S可以承受15 kV的电压，但陶瓷贴片电容对高压的承受能力比较弱。

5 kV的冲击就会造成约10％陶瓷电容失效，而到10 kV时，其损坏率将高达到60％。

1.2 TVS二极管的主要参数(1)最小击穿电压VBR当TVS流过规定的电流时，TVS两端的电压称为最小击穿电压，在此区域，TV S呈低阻抗的通路。

在25℃时，低于这个电压，TVS是不会发生雪崩击穿的。

(2)额定反向关断电压VWMVWM是TVS在正常状态时可承受的电压，此电压应大于或等于被保护电路的正常工作电压。

但它又需要尽量与被保护电路的正常工作电压接近，这样才不会在TVS工作以前使整个电路面对过压威胁。

按TVS的VBR与标准值的离散度，可把VBR分为5％和10％两种，对于5％的VBR来说，VWM=0.85VBR腿；而对于10％的VBR来说，VW M=0.81VBR。

(3)最大峰值脉冲电流IPPIPP是TVS在反向状态工作时，在规定的脉冲条件下，器件允许通过的最大脉冲峰值电流。

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。

TVS二极管详解

TVS二极管详解一.特性定义TVS二极管，又称瞬态抑制二极管，是普遍使用的一种新型高效电路保护器件，它具有极快的响应时间和相当高的浪涌吸收能力。

当它的两端经受瞬间的高能量冲击时，TVS能以极高的速度把两端间的阻抗值由高阻抗变为低阻抗，以吸收一个瞬间大电流，把它的两端电压箝制在一个预定的数值上，从而保护后面的电路元件不受瞬态高压尖峰脉冲的冲击。

特点TVS能承受的瞬时脉冲功率可达上千瓦，其箝位响应时间仅为1ps（10^-12S）。

TVS允许的正向浪涌电流在T =25℃，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，并把电压箝制到预定水平，双向TVS适用于交流电路，单向TVS一般用于直流电路。

TVS器件分类：按极性可分为：单极性和双极性两种；按用途可分为：通用型和专用型；按封装和内部结构可分为：轴向引线二极管、双列直插TVS阵列、贴片式和大功率模块等。

轴向引线的产品峰值功率可达400W、500W、600W、1500W 和5000W。

其中大功率的产品主要用在电源馈线上，低功率产品主要用在高密度安装场合。

对于高密度安装的场合，也可以选择双列直插和表面贴装等封装形式。

深圳市赛特微电子有限公司二、介绍与应用便携式设备的ESD保护十分重要，而TVS二极管是一种十分有效的保护器件，与其它器件相比有其独特的优势，但在应用时应当针对不同的保护对象来选用器件，因为不同的端口可能受到的静电冲击有所不同，不同器件要求的保护程度也有不同。

要注意相应的参数鉴别以及各个生产商的不同设计，同时还要进行合理的PCB布局。

在这里介绍下便携式设备的ESD保护中如何应用TVS二极管器件。

便携式设备如笔记本电脑、手机、PDA、MP3播放器等，由于频繁与人体接触极易受到静电放电(ESD)的冲击，如果没有选择合适的保护器件，可能会造成机器性能不稳定，或者损坏。

一般情况下，对此类设备暴露在外面可能与人体接触的端口都要求进行防静电保护，如键盘、电源接口、数据口、I/O口等等。
