瞬变二极管的主要参数

瞬变二极管参数说明如下

流回路应用十分方便

三：TVS器件的主要电参数

1.击穿电压N(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。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，因此，TVS能抑制可能出现的脉冲功率的冲击，从而有效地保护电子线路。

峰值电流波形

A、正弦半波B，矩形波

C.标准波（指数波形）

D.三角波

TVS峰值电流的试验波形采用标准波（指数波形）。由TR/TP决定。峰值电流上升时间TR:电流从0.1IPP开始到0.9IPP的时间。半峰值电流时间TP“电流从零开始通过最大峰值后，下降到0.5IPP值的时间。

下面列出典型试验波形的TR/TP值

A.EMP波：10Ns/1000nS

B.闪电波：8uS/0uS C、标准波：10Us/000uS

3.最大反向工作电压VRWM(或变位电压)

器件反向工作时，在规定的IR下，器件两端的电压值称为最大反向工作电压VRWM通常VRWM=(0.8～0.9)B(BR)

功率消耗很小，使用时，应使用VRWM不低于被保护器件或线路的正常工作电压，

4.最大箝位电压VC(max)

有脉冲峰值电流IPP作用下器件两端的最大电压值称为最大箝位电压，使用时应使VC(max)不高于被保护器件的

最大允许安全电压，最大箝位电压与击穿电压之比称为箝位系数。即：箝位系数=VC(max)/V(BR) 一般箝位系数1.3左右。

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。
