tvs瞬态抑制二极管参数

TVS瞬态抑制二极管参数1. 介绍瞬态抑制二极管（Transient Voltage Suppressor Diode，简称TVS二极管）是一种用于保护电子电路免受瞬态电压干扰的器件。

它可以有效地抑制过电压和过电流，保护电路中的其他元件不受损坏。

本文将重点介绍TVS瞬态抑制二极管的参数，包括其电气参数、封装参数和可靠性参数。

2. 电气参数2.1 额定电压（Vr）额定电压是指TVS二极管能够正常工作的最大电压。

当电压超过额定电压时，TVS二极管将开始导通，以保护电路免受过电压的影响。

2.2 尖峰脉冲功率（Ppp）尖峰脉冲功率是指TVS二极管能够吸收的瞬态脉冲能量。

它表示了TVS二极管在瞬态电压出现时能够承受的最大功率。

通常情况下，尖峰脉冲功率越大，TVS二极管的抑制能力越强。

2.3 最大反向峰值电流（Ipp）最大反向峰值电流是指TVS二极管能够承受的最大反向电流。

当电路中的电压超过额定电压时，TVS二极管将导通，使电流通过，以保护电路。

最大反向峰值电流越大，TVS二极管的抑制能力越强。

2.4 动态电阻（Rd）动态电阻是指TVS二极管在导通状态下的电阻。

动态电阻越小，TVS二极管的抑制能力越强。

因此，低动态电阻是衡量TVS二极管性能好坏的重要指标之一。

3. 封装参数3.1 封装类型TVS瞬态抑制二极管有多种封装类型可供选择，常见的封装类型有DO-214、SMA、SMB等。

不同的封装类型适用于不同的应用场景。

选择合适的封装类型可以提高电路的可靠性和稳定性。

3.2 封装尺寸封装尺寸是指TVS二极管的外部尺寸。

在进行电路设计时，需要考虑TVS二极管的封装尺寸是否符合电路板的布局要求，以确保TVS二极管能够正确安装在电路板上。

3.3 焊接温度焊接温度是指TVS二极管在焊接过程中所能承受的最高温度。

在进行电路组装时，需要控制焊接温度，避免超过TVS二极管的最大焊接温度，以免影响其性能和可靠性。

4. 可靠性参数4.1 工作温度范围工作温度范围是指TVS二极管能够正常工作的温度范围。

TVS 命名规则
嗨，亲爱的小伙伴们！今天咱们来聊聊 TVS 命名那些事儿。

TVS 啊，就是瞬态电压抑制二极管，它在电路保护里可是个厉害的角色。

那它的名字咋来的呢？这里面的规则可得搞清楚。

先说命名里的数字，这可重要啦！比如“SMBJ5.0CA”，这里的“5.0”就表示它的击穿电压是 5 伏。

可别小看这数字，它决定了 TVS 啥时候开始干活保护电路。

要是电压超过了这个数，TVS 就会挺身而出，把多余的电压给“吞掉”。

再看看字母，像“SMB”，这是封装形式。

不同的封装，大小、形状啥的都不一样，得根据你的电路设计来选。

要是选不对，那可就麻烦啦，装都装不进去！
还有些命名里会有“C”或者“A”，这代表着不同的极性。

“C”一般是双向的，两边电压高了都能保护；“A”呢，就是单向的，只能一个方向保护。

那命名规则里禁止啥呢？可千万别乱编字母数字，也别随便拿个名字就说是 TVS 的正规命名。

这会让人摸不着头脑，搞不清楚这 TVS 到底是啥参数啥特性。

举个例子哈，要是有人把一个 TVS 命名成“ABC123”，没有遵循正
常的规则，那工程师们看到肯定得晕头转向，不知道该咋用这个 TVS 了。

总之，TVS 的命名规则就像给它的一张身份证，清楚准确地告诉我
们它的特性和能力。

咱们按照规则来，就能选对合适的 TVS，让电路
稳稳当当的，不出岔子。

所以啊，记住这些命名规则，咱们在电路设计的时候就能顺顺利利，让 TVS 好好发挥作用，保护咱们的电路安全！好啦，关于 TVS 命名规则就说到这儿，希望对大家有帮助哟！。

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PPR大于被保护器件或线路可能出现的最大瞬态浪涌功率。

图1-3表明当瞬时脉冲峰值电流出现时，TVS被击穿，并由击穿电压值上升至最大箝位电压值，随着脉冲电流呈指数下降，箝位电压亦下降，恢复到原来状态。

一文详解瞬态电压抑制二极管,看完再也不怕被忽悠了

一文详解瞬态电压抑制二极管，看完再也不怕被忽悠了提及电路保护元器件，对于行业人而言，能够夸夸其谈，三天三夜都说不完；而对于行外人或者刚入门的人而言，犹如看天书，稍不慎，很容易掉进盲区。

不可否认，在这个网络信息技术发达的时代，关于tvs管各种各类的信息随处可见，但，其真正有多少是专业、科学的，都有待考究和甄别。

为此，东沃电子，特意为大家科普下关于瞬态电压抑制二极管这方面的知识。

何为tvs管，有什么作用？TVS（Transient Voltage Suppressor）管，也称瞬态电压抑制二极管，是在齐纳二极管工艺基础上发明的一种新型高效电路保护元器件，p秒级别的响应时间和高浪涌吸收能力是tvs管的核心优势。

tvs管的工作原理，与常见的齐纳二极管极其相似，在一定范围内，均可以限制电路中两端的电压，使得两极间的电压箝位稳定在一个安全值，从而有效地保护电路中的精密元器免受破坏高压、高流、高涌破坏。

目前，tvs管广泛应用在家用电器、计算机系统、通讯设备、汽车电子、交/直流电源、电子镇流器、工业控制、医学、航空等方面。

如何区分tvs管的正负极和单双向？当瞬态电压抑制二极管这个产品在您手上时候，第一时间，要知道这个产品的正负极和单双向。

1）看标志：tvs管，有单向和双向之分，单向的一端呢，有细色环，接的是正极，而双向的呢，中间有两道环，或者没有任何标志，没极性。

2）看规格书：一般在第一页，双向为双向导通，单向为单向导通。

3）看型号：tvs管的型号命名是有规律的，大部分tvs管型号均能看出参数，具体可以咨询东沃电子，一家真正专注于电路保护元器件研发、生产、销售为一体的新兴企业。

4）借助万用表工具：单向一边又电压，直流方面有雪崩击穿特性；双向都有电压，直流方面，双向对称。

如何选择tvs管的型号？关于tvs管型号选择这个问题，东沃电子曾科普了很多这方面的知识。

在这里，就简单总结几点，如有不懂之处，东沃电子的技术人员随时随地为您解答，根据您的需求推荐最适合您的产品。

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管主要参数说明及作用

TVS管主要参数说明及作用TVS管，全称为Transient Voltage Suppressor，也称为TVS二极管、瞬态电压抑制二极管，是一种用于保护电子设备免受瞬态电压冲击的电子元件。

它可以在电路中提供瞬态电压保护，确保电压在安全范围内，从而防止电路过压破坏和损坏。

主要参数说明及作用如下：1.峰值反向电压（VBR）：指代TVS管正常工作时可承受的最大反向电压。

它决定了TVS管保护的电路在有过压冲击时所能承受的最高电压。

当电路的电压超过VBR时，TVS管将启动工作，将过剩的能量引流到地。

2.峰值脉冲功率（PPM）：表示TVS管允许通过的最大脉冲功率，通常以瓦特（W）为单位。

它决定了TVS管在短时间内能够吸收的能量。

3.瞬态响应时间（tR）：指TVS管从未激发状态到达10%、50%、90%等特定电压的时间。

响应时间越短，TVS管对过压冲击的响应能力越强。

4.电流容量（IT）：表示TVS管能够承受的最大经过电流。

它是决定TVS管稳定工作的重要参数，过大的电流可能造成TVS管烧毁。

5.浪涌容量（PPM）：表明TVS管在一定时间内可以吸收的过电压能量，通常以焦耳（J）为单位。

浪涌容量越大，TVS管对过电压冲击的吸收能力越强。

6. 电压温度系数（VBR Temperature Coefficient）：TVS管工作温度变化时，峰值反向电压的变化率。

该系数可以衡量TVS管在不同温度下的反向电压稳定性。

7. 工作温度范围（Operating Temperature Range）：TVS管能够正常工作的温度范围。

TVS管的作用在于保护电子设备免受过电压的破坏。

当电路中出现过电压时，TVS管会迅速打开，将过剩的能量引流到地，从而保护其他电子元件。

TVS管可以防止过电压对电子设备产生破坏或失效，并提供短路保护。

它广泛应用于各种电子设备中，如电源、通信设备、计算机、汽车电子等。

需要注意的是，不同应用场景下TVS管的参数需求各不相同。
