描述

可控硅是P1N1P2N2四層三端結(jié)構(gòu)元件，共有三個(gè)PN結(jié)，分析原理時(shí)，可以把它看作由一個(gè)PNP管和一個(gè)NPN管所組成，其等效圖解如右圖所示。雙向可控硅：雙向可控硅是一種硅可控整流器件，也稱作雙向晶閘管。這種器件在電路中能夠?qū)崿F(xiàn)交流電的無(wú)觸點(diǎn)控制，以小電流控制大電流，具有無(wú)火花、動(dòng)作快、壽命長(zhǎng)、可靠性高以及簡(jiǎn)化電路結(jié)構(gòu)等優(yōu)點(diǎn)。從外表上看，雙向可控硅和普通可控硅很相似，也有三個(gè)電極。但是，它除了其中一個(gè)電極G仍叫做控制極外，另外兩個(gè)電極通常卻不再叫做陽(yáng)極和陰極，而統(tǒng)稱為主電極Tl和T2。它的符號(hào)也和普通可控硅不同，是把兩個(gè)可控硅反接在一起畫成的，如圖2所示。它的型號(hào)，在我國(guó)一般用“3CTS”或“KS”表示；國(guó)外的資料也有用“TRIAC”來(lái)表示的。雙向可控硅的規(guī)格、型號(hào)、外形以及電極引腳排列依生產(chǎn)廠家不同而有所不同，但其電極引腳多數(shù)是按T1、T2、G的顧序從左至右排列(觀察時(shí)，電極引腳向下，面對(duì)標(biāo)有字符的一面)。市場(chǎng)上最常見的幾種塑封外形結(jié)構(gòu)雙向可控硅的外形及電極引腳排列如下圖1所示。

Thyristor is a P1N1P2N2 four layer three terminal structural element with three PN junctions. When analyzing the principle, it can be regarded as composed of a PNP transistor and an NPN transistor, and its equivalent diagram is shown in the right figure. Bidirectional thyristor: Bidirectional thyristor is a silicon controlled rectifier device, also known as a bidirectional thyristor. This device can achieve contactless control of AC power in circuits, controlling large currents with small currents. It has the advantages of no sparks, fast action, long service life, high reliability, and simplified circuit structure. From the appearance, bidirectional thyristor is very similar to ordinary thyristor, with three electrodes. However, except for one electrode G, which is still called the control electrode, the other two electrodes are usually no longer called the anode and cathode, but collectively referred to as the main electrodes Tl and T2. Its symbol is also different from that of ordinary thyristors, which is drawn by reversing the connection of two thyristors together, as shown in Figure 2. Its model is generally represented by “3CTS” or “KS” in China; Foreign data can also be represented by ‘TRIAC’. The specifications, models, appearance, and electrode pin arrangement of bidirectional thyristor vary depending on the manufacturer, but most of its electrode pins are arranged from left to right in the order of T1, T2, and G (when observed, the electrode pins are facing downwards and facing the side marked with characters). The appearance and electrode pin arrangement of the most common plastic encapsulated structure bidirectional thyristor in the market are shown in Figure 1.
