SA13CA,TVS瞬变抑制二极管中文资料

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。
