【应用】用于EML过滤的瞬态抑制二极管，能在电容器上节省成本且避免过电压发生爆炸

时间： 2018-10-22 来源：LITTELFUSE

技术问答

SMPS的设计多采用大型且昂贵的电解滤波电容器。它们对于过电压现象非常敏感，而且有可能发生严重故障并产生巨大的爆炸声。为避免发生这种情况，设计师们通常会给这些电容器设定较高的额定电压值。

瞬态抑制二极管提供的箝位电压非常精确，因而设计师通常可以使用额定电压值较低的电容器。在电容器上节省的成本通常不仅足以支付瞬态抑制二极管的费用，同时还能降低成本，实现更为稳定的设计。 TVS的电压值需要慎重选择，该数值应该高于最大线路电压但低于电容器的额定电压。输入端如配备了MOV，大部分的设计都可以使用LITTELFUSE推出的SMBJ350CA瞬态抑制二极管。除外，P6KE350CA瞬态抑制二极管同样适用于本方案。

根据接受保护的不同产品，标准亦有变化。标准包括：IEC 61000-4-5 UL 1950 IEC 950。

用于EML过滤的瞬态抑制电路图

P6KE350CA瞬态抑制二极管最高温度系数ΔVBR = 0.1% x VBR@25°C，10×1000μs波形时的峰值脉冲功率为600W，重复频率（工作循环）为0.01%。电压高于13V时，标准IR小于1μA，可保证高温焊接265°C/10秒/。引线长度为0.375英寸（9.5毫米），张力为51磅（2.3公斤）。专门用于保护敏感电子设备，使其免受雷击和其他瞬态电压事件引起的瞬态电压侵害。

另一款SMBJ350CA瞬态抑制二极管的电压高于12V时，I_R通常小于1μA，可优化电路板空间的表面贴装型产品。保证高温焊接，接线端260°C/40秒。同样专门用于保护敏感电子设备，使其免受雷击和其他瞬态电压事件引起的瞬态电压侵害。

【技术】浅析瞬态抑制二极管（双向TVS管）

TVS管也叫瞬态抑制二极管，TVS管是吸收浪涌功率用的，能在极短时间内承受反向电压冲击，使两极间的电压钳位于一个特定电压上，避免后面的电路受到冲击。简单的说就是做过压保护的，在通信等产品中很常见。连接时必须反向工作在电路电源、地两端，与稳压二极管类似，但不需要限流电阻。
