5SHY4045L 0004晶闸管是一种由硅制成的单向半导体器件，基本上晶闸管(SCR)是- 种三端子四层半导体器件，由交替的P型和N型材料组成。

5SHY4045L0004晶闸管具有三个pn结J 1、J 2和J3，下图显示了賄pnpn层的晶闸管。晶闸管具有端子阳极(A)、阴极(K)和栅极G),(G)连接到靠近
阴极(K)端子的p层。

5SHY4045L0004晶体管四层像两个晶体管一样工作,它们连接在一起(如下图所示)，一个的输出形成另-一个的输入，门作为-种“启动马达”来激活它们。

5SHY4045L0004单个晶闸管(SCR)是-个pnp晶体管(Q 1 )和一个npn晶体管
(Q2 )的组合。这里，Q1的发射极作为SCR，而Q2的发射极是它的阴极。另外, Q1的基极与Q2的集电极连接，Q1的集电极与Q的基极连接，晶闸管的也连接到Q2的基极。

The 5SHY4045L 0004 thyristor is a unidirectional semiconductor device made of silicon, basically a thyristor
SCR is a three-terminal, four-layer semiconductor device consisting of alternating P-type and N-type materials.

The 5SHY4045L0004 thyristor has three pn junctions J1, J2 and J3. The figure below shows the thyristor of the pnpn layer. The thyristor has A terminal anode (A), cathode (K), and gate G), with (G) connected to close
p layer of cathode (K) terminal.

The 5SHY4045L0004 transistor four layers work like two transistors, they are connected together (as shown below), the output of one forms the input of the other, and the gate acts as a kind of "starter motor" to activate them.

The 5SHY4045L0004 Single thyristor (SCR) is a pnp transistor (Q1) and an npn transistor
The combination of (Q2). Here, Q1's emitter is the SCR, and Q2's emitter is its cathode. In addition, the base of Q1 is connected to the collector of Q2, the collector of Q1 is connected to the base of Q, and the thyristor is also connected to the base of Q2.
