TVS DIODE :瞬态抑制二极管是一种限压型的过电压保护器件,它又叫TVP、ABD，它能以pS级的速度把过高的电压限制在一个安全范围之内，从而起到保护后面电路的作用。 广泛应用在半导体及敏感的电子零件过电压、ESD保护上，主要包括：消费类产品、工业产品、通讯、电脑、汽车、电源供应品、信号线路保护及军事、航天航空导航系统及控制系统上; 反应速度快,电压抑制能力强，有P4KE 、 P6KE 、 1.5KE 、 SA 、3KP、 5KP SMAJ、 SMBJ 、SMCJ 、 P4SMA、 P6SMB、 1.5SMC、等系列。 限压型零件,反应速度快 瞬态功率从400W至5000W; 电压由5V至550V或更高,也可为客户定制规格。 TVS 的选用技巧
1、确定被保护电路的最大直流或连续工作电压、电路的额定标准电压
2、TVS额定反向关断VWM 应大于或等于被保护电路的最大工作电压。若选用的VWM 太低，器件可能进入雪崩或因反向漏电流太大影响电路的正常工作。串行连接分电压，并行连接分电流。
3、 TVS 的最大箝位电压VC 应小于被保护电路的损坏电压。
4、在规定的脉冲持续时间内，TVS 的最大峰值脉冲功耗PM 必须大于被保护电路内可能出现的峰值脉冲功率。在确定 最大箝位电压后，其峰值脉冲电流应大于瞬态浪涌电流。
5、对于数据接口电路的保护，还必须注意选取具有合适电容C 的TVS 器件。
6、根据用途选用TVS 的极性及封装结构。交流电路选用双极性TVS较为合理；多线保护选用TVS 阵列更为有利。
7、温度考虑。瞬态电压抑制器可以在－55~+150℃之间工作。如果需要TVS 在一个变化的温度 工作，由于其反向漏电流ID是随温度增加而增大；功耗随TVS结温增加而下降，从+25℃到+175℃，大约线性下降50%击穿电压VBR 随温度的增加按一定的系数增加。因此，考虑温度变化对其特性的影响。
