可控硅（Silicon Controlled Rectifier，简称SCR）是一种大功率电器元件，也被称为晶闸管。它具有体积小、效率高、寿命长等优点。在自动控制系统中，可控硅可作为大功率驱动器件，通过小功率控件实现控制大功率设备的功能。可控硅在交直流电机调速系统、调功系统及随动系统中得到了广泛的应用。

3BHB003154R0101 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。在结构上，双向可控硅相当于两个单向可控硅反向连接，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。这种装置的优点是控制电路简单，没有反向耐压问题，因此特别适合做交流无触点开关使用。

此外，3BHB003154R0101 可控硅是一种具有三个PN结的四层结构的大功率半导体器件，一般由两晶闸管反向连接而成。它的出现使半导体技术从弱电领域进入了强电领域，成为工业、农业、交通运输、军事科研以至商业、民用电器等方面争相采用的元件。

Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, the thyristor can be used as a high-power driving device, and the function of controlling high-power equipment can be realized through the low-power control. SCR has been widely used in AC and DC motor speed control system, power regulation system and servo system.

3BHB003154R0101 thyristor is divided into unidirectional thyristor and bidirectional thyristor. Bidirectional thyristor is also called TRIAC, or TRIAC for short. In terms of structure, the bidirectional thyristor is equivalent to two one-way thyristors in reverse connection, with double guiding function. Its on-off state is determined by the control pole G, and adding a positive pulse (or negative pulse) to the control pole G can make it forward (or reverse) on. The advantage of this device is that the control circuit is simple and there is no reverse voltage problem, so it is particularly suitable for AC contactless switch use.

In addition, the 3BHB003154R0101 thyristor is a high-power semiconductor device with a four-layer structure of three PN junctions, which is generally made of two thyristors connected in reverse. Its emergence makes semiconductor technology enter the field of strong electricity from the field of weak electricity, and become the components that are used in industry, agriculture, transportation, military scientific research, as well as commercial and civilian electrical appliances.
