ABB 5SDF0860H0003 可控硅 IGBT 库存备货

ABB 5SDF0860H0003 单晶闸管（SCR）是一个 pnp 晶体管（Q 1）和一个 npn 晶体管（Q 2）的组合。在这里，Q1 的发射极是可控硅的阳极，Q2 的发射极是阴极。此外，Q1 的基极与 Q2 的集电极相连，Q1 的集电极与 Q 的基极相连，晶闸管的栅极也与 Q2 的基极相连。

ABB 5SDF0860H0003  A single thyristor (SCR) is a combination of a pnp transistor (Q 1) and an npn transistor (Q 2). Here, Q1’s emitter is the anode terminal of the SCR, and Q2’s emitter is its cathode. In addition, the base of Q1 is connected to Q2’s collector, the collector of Q1 is connected to Q’s base, and the gate terminal of the thyristor is also connected to Q2’s base.

ABB 5SDF0860H0003 四层晶体管的工作原理就像两个晶体管，它们连接在一起，其中一层晶体管的输出端构成另一层晶体管的输入端，而栅极则充当一种 "启动电机 "来激活它们。
