三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)和(he)(he)二(er)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)都是(shi)半導體(ti)器件，但它(ta)們(men)的(de)(de)作(zuo)用和(he)(he)結構有(you)很大的(de)(de)不(bu)(bu)同。二(er)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)只有(you)兩個電(dian)極(ji)(ji)(ji)(ji)，即(ji)正(zheng)極(ji)(ji)(ji)(ji)和(he)(he)負極(ji)(ji)(ji)(ji)。它(ta)的(de)(de)主要(yao)(yao)(yao)作(zuo)用是(shi)將電(dian)流限制在(zai)一個方(fang)向上，即(ji)只能(neng)從正(zheng)極(ji)(ji)(ji)(ji)流向負極(ji)(ji)(ji)(ji)，而不(bu)(bu)能(neng)反向流動(dong)。因此，二(er)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)通常用于整流電(dian)路中。而三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)有(you)三(san)個電(dian)極(ji)(ji)(ji)(ji)，即(ji)發射極(ji)(ji)(ji)(ji)、基(ji)極(ji)(ji)(ji)(ji)和(he)(he)集(ji)電(dian)極(ji)(ji)(ji)(ji)。它(ta)的(de)(de)主要(yao)(yao)(yao)作(zuo)用是(shi)放(fang)大電(dian)流和(he)(he)控(kong)制電(dian)流。當電(dian)流從基(ji)極(ji)(ji)(ji)(ji)流入(ru)時，它(ta)可以控(kong)制從集(ji)電(dian)極(ji)(ji)(ji)(ji)流出的(de)(de)電(dian)流大小。因此，三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)通常用于放(fang)大電(dian)路和(he)(he)開(kai)關電(dian)路中。此外，三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)的(de)(de)結構比(bi)二(er)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)更加復雜，需要(yao)(yao)(yao)更多的(de)(de)工藝(yi)步驟來制造。因此，三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)的(de)(de)成本也比(bi)二(er)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)高。東莞(guan)發光三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)供應商家三(san)極(ji)(ji)(ji)(ji)管(guan)(guan)(guan)(guan)(guan)的(de)(de)熱(re)耗散(san)問題需要(yao)(yao)(yao)充分考慮并實施相應的(de)(de)散(san)熱(re)措施。
