5SHX06F6004 可控硅主板 

5SHX06F6004 可控硅分单向可控硅和双向可控硅两种。双向可控硅也叫三端双向可控硅，简称TRIAC。双向可控硅在结构上相当于两个单向可控硅反向连接，这种可控硅具有双向导通功能。其通断状态由控制极G决定。在控制极G上加正脉冲(或负脉冲)可使其正向(或反向)导通。

5SHX06F6004 Thyristors are divided into two types: unidirectional thyristors and bi-directional thyristors. Bidirectional thyristors are also called triacs, or TRIACs for short. bi-directional thyristors are structurally equivalent to two unidirectional thyristors connected in reverse, and this type of thyristor has a bi-directional conduction function. The on/off state is determined by the control pole G. A positive pulse is applied to the control pole G. In the control pole G plus a positive pulse (or negative pulse) can make its positive (or reverse) conduction.

5SHX06F6004 可控硅优点，例如:以小功率控制大功率，功率放大倍数几十万;反应极快，在微秒级内开通、关断;无触点运行，无火花、无噪音;效率高，成本低等等。

5SHX06F6004 Advantages of SCRs，such as: small power control of high power, power amplification up to hundreds of thousands of times; fast response, in microseconds within the open, shutdown; non-contact operation, no sparks, no noise;, high efficiency, low cost and so on.

5SHX06F6004 可控硅的弱点:静态及动态的过载能力较差;容易受干扰而误导通。可控硅从外形上分类主要有:螺栓形、平板形和平底形。
