技术问答

本文将介绍TVS二极管的选用技巧，以及硕凯电子提供的TVS二极管常用型号。

TVS二极管选用技巧：

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和“高端”容限。

2、 TVS额定反向关断V_WM应大于或等于被保护电路的最大工作电压。若选用的V_WM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V_C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P_M必须大于被保护电路内可能出现的峰值脉冲功率。在确定了最大箝位电压后，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I_D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V_BR随温度的增加按一定的系数增加。因此，必须查阅有关产品资料，考虑温度变化对其特性的影响。

硕凯电子提供的TVS二极管，根据封装形式分为贴片型与轴向引线型两大类，具体如下：

贴片型：

1、DO-214AC/SMA： SMAJ(400W) P4SMA (400W)

2、DO-214AA/SMB： SMBJ(600W) P6SMB(600W ）

3、DO-214AB/SMC： SMCJ(1.5KW) SMDJ (3KW) 1.5SMC(1.5KW) 5.0SMDJ(5KW)

引线型：

4、DO-201AL/DO-41：P4KE(400W)

5、DO-204AC/DO-15：P6KE (600W) SA (500W) SAC(500W，50pF，±10%)

6、DO-201AE：1.5KE (1.5KW) LCE(1.5KW，100pF)

7、P600：3KP(3KW) 5KP(5KW) 15KPA(KW) 20KPA(20KW) 30KPA(30KW)

【经验】如何区分瞬态抑制二极管的方向

TVS二极管在测试前要先区分其单双向。虽然最终的作用是一样的，但是单双向TVS二极管的适用范围还是有差别的，双向TVS管适用于交流电路，单向TVS管一般用于直流电路。本文的目的是教大家如何区分瞬态抑制二极管的方向。
