【选型】如何选用TVS瞬态抑制二极管？
TVS（transient voltage suppressor）意思是瞬态电压抑制器。TVS管原理和稳压二极管类似，都是利用反向击穿稳定电压（TVS管为雪崩效应）。不过TVS管的响应速度要远远快于稳压管。当TVS管的受到反向瞬态高能量冲击时，它能以速度（亚纳秒级）将两级间的阻抗变为低阻抗，从而将浪涌吸收掉，同时也维持两级电压在一个预定值，有效的保护电路中元器件，避免元器件受浪涌脉冲导致损坏。
LITTELFUSE的TVS涵盖工业级产品和车规级产品，稳压值上TVS管2.5V～430V 。TVS响应时间可以低至1ps。电容值可低至零点几PF。要理解TVS的选用，我们需通过Datasheet的几个主要参数来看，先了解主要参数的意义。
图1：Littelfuse的SMBJ系列datasheet
1：REVERSE STAND-OFF VOLTAGE VRWM (Volts) 反向峰值电压, 为TVS管的工作电压。该电压下，TVS管两端的电阻很大，这就保证了TVS管吸收的电流可以忽略不计。一般应用时，这个值等于或略大于正常工作电压。
2：BREAKDOWN VOLTAGE VBR(V) MIN & MAX @IT 反向击穿电压，该参数为直流电流IT条件下，测量的反向电压值。该项表明器件进入反向雪崩击穿的电压值。
3：TEST CURRENT IT(mA) 测试电流，用来规定器件的反向击穿电压值。
4：MAXIMUM CLAMPING VOLTAGE @IPP Vc(V)最大钳位电压，在规定的脉冲时间tr内，承受的最大峰值电流Ipp条件下加在器件上的最大电压值。
5：PEAK PULSE CURRENT IPP(A) 最大脉冲电流，在规定的时间tr内，器件所允许通过的最大峰值脉冲电流。
6：REVERSE LEAKAGE @VRWM IR(uA) 反向漏电流，即在工作电压VRWM时，流经TVS管的反向电流。
7：Cj Junction Capacitance 接电容，主要指TVS和GND或IO连接时，具有的电容值。
8：还有部分作为高速IO上保护的TVS，还会给出insert loss @ Freq。以便确认是否能作为保护器件。
了解上诉参数后，在实际应用电路上，一般采用的选型原则是：
① TVS额定反向关断电压VRWM应大于或等于被保护电路的最大工作电压。 （例如图1中SMBJ5.0A，VRWM为5V。应用平均电压需≤5V）
② 最小击穿电压VBR=VRWM/KBR (其中，一般KBR=0.8～0.9)【例如图1的SMBJ6.0A，最小的VBR为6.67V，KBR=0.89，最小VBR为雪崩效应启动电压】
③ TVS的最大箝位电压VC应小于被保护电路的损坏电压，即VC=KC×VBR (其中，KC=1.3)，【例如图1的SMBJ6.0A，VC=10.3V，选用时的VC值需小于后端保护器件端口能承受的最大电压值】。
④ 在规定的脉冲持续时间内，TVS标称的最大峰值脉冲功耗PM必须大于实际应用时的脉冲功耗。在确定了最大箝位电压后，TVS的峰值脉冲电流应大于实际应用的瞬态浪涌电流。
通过上诉描述，相信对你在TVS选用上有所帮助，另外Littelfuse品牌基本涵盖全系列的TVS可供选型。Littelfuse的TVS选型指南，包括工业和车规产品在内：https://www.sekorm.com/doc/89495.html

【技术】TVS管与ESD保护二极管的区别
TVS管与ESD保护二极管的区别？TVS管和ESD管的区别是：工作原理是一样的，但功率和封装是不一样的；ESD主要是用来防静电，防静电就要求电容值低，TVS就做不到这一点，TVS的电容值比较高。具体的区别还有哪些？和里阳半导体一起来看看吧。
