電流I2l的方向從T2流向T1。由特性曲線可知，這時(shí)雙向可控硅觸發(fā)導(dǎo)通規(guī)律是按象限的特性進(jìn)行的，又因?yàn)橛|發(fā)是正向的，所以把這種觸發(fā)叫做“象限的正向觸發(fā)”或稱(chēng)為I+觸發(fā)。(2)如果主電極T2仍加正向電壓，而把觸發(fā)改為反向(圖5b)，這時(shí)雙向可控硅觸發(fā)導(dǎo)通后，通態(tài)電流的方向仍然是從T2到T1。我們把這種觸發(fā)叫做“象限的負(fù)觸發(fā)”或稱(chēng)為I-觸發(fā)。(3)兩個(gè)主電極加上反向電壓U12(圖5c)，輸入正向觸發(fā)，雙向可控硅導(dǎo)通后，通態(tài)電流從T1流向T2。雙向可控硅按第三象限特性曲線工作，因此把這種觸發(fā)叫做Ⅲ+觸發(fā)。(4)兩個(gè)主電極仍然加反向電壓U12，輸入的是反向觸發(fā)(圖5d)。
