在實際選(xuan)用光(guang)(guang)(guang)(guang)敏三極管(guan)時(shi),應注(zhu)意按參數要(yao)求選(xuan)擇(ze)管(guan)型。如要(yao)求靈敏度(du)高,可(ke)(ke)選(xuan)用達林頓(dun)型光(guang)(guang)(guang)(guang)敏三極管(guan);如要(yao)求響應時(shi)間快,對溫度(du)敏感(gan)性小,就不選(xuan)用光(guang)(guang)(guang)(guang)敏三極管(guan)而選(xuan)用光(guang)(guang)(guang)(guang)敏二(er)極管(guan)。探(tan)測暗光(guang)(guang)(guang)(guang)一(yi)(yi)定要(yao)選(xuan)擇(ze)暗電(dian)(dian)流小的(de)管(guan)子,同時(shi)可(ke)(ke)考慮有基極引出(chu)線(xian)的(de)光(guang)(guang)(guang)(guang)敏三極管(guan),通(tong)過(guo)偏置(zhi)取得合適的(de)工(gong)作(zuo)點,提高光(guang)(guang)(guang)(guang)電(dian)(dian)流的(de)放(fang)大(da)系數。總之,光(guang)(guang)(guang)(guang)電(dian)(dian)三極管(guan)工(gong)作(zuo)原理分(fen)為兩個過(guo)程:一(yi)(yi)是光(guang)(guang)(guang)(guang)電(dian)(dian)轉換;二(er)是光(guang)(guang)(guang)(guang)電(dian)(dian)流放(fang)大(da)。比較大(da)特點是輸出(chu)電(dian)(dian)流大(da),達毫(hao)安級。但(dan)響應速度(du)比光(guang)(guang)(guang)(guang)電(dian)(dian)二(er)極管(guan)慢得多,溫度(du)效應也比光(guang)(guang)(guang)(guang)電(dian)(dian)二(er)極管(guan)大(da)得多。河(he)北多功(gong)能光(guang)(guang)(guang)(guang)電(dian)(dian)二(er)極管(guan)的(de)作(zuo)用光(guang)(guang)(guang)(guang)電(dian)(dian)二(er)極管(guan)的(de)其他應用有:用作(zuo)光(guang)(guang)(guang)(guang)傳感(gan)器的(de)光(guang)(guang)(guang)(guang)電(dian)(dian)二(er)極管(guan)。
光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)是pn結或(huo)PIN配置。如果光(guang)(guang)(guang)(guang)子撞(zhuang)擊二極管(guan)(guan)(guan)(guan),它(ta)將(jiang)產(chan)生(sheng)(sheng)電(dian)(dian)(dian)子和帶正電(dian)(dian)(dian)的(de)(de)空穴。當(dang)在結的(de)(de)耗盡區發生(sheng)(sheng)任何吸(xi)收時(shi),這(zhe)些載(zai)流(liu)子已從該耗盡區的(de)(de)內置區域(yu)捕獲在結中,從而產(chan)生(sheng)(sheng)了光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)流(liu)。光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)在反偏(pian)(pian)(pian)壓下或(huo)無(wu)偏(pian)(pian)(pian)壓下被廣大(da)使用。光(guang)(guang)(guang)(guang)或(huo)光(guang)(guang)(guang)(guang)子可以驅(qu)動電(dian)(dian)(dian)流(liu)流(liu)過該電(dian)(dian)(dian)路(lu),從而產(chan)生(sheng)(sheng)正向(xiang)(xiang)(xiang)偏(pian)(pian)(pian)置,從而導致從反方(fang)向(xiang)(xiang)(xiang)到光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)流(liu)的(de)(de)“暗電(dian)(dian)(dian)流(liu)”。這(zhe)被稱為自然效應,可以作(zuo)為太(tai)陽能電(dian)(dian)(dian)池設計的(de)(de)基礎。太(tai)陽能電(dian)(dian)(dian)池板(ban)只是多個有效光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)的(de)(de)組(zu)合(he)。反向(xiang)(xiang)(xiang)偏(pian)(pian)(pian)置會沿完全相(xiang)同的(de)(de)方(fang)向(xiang)(xiang)(xiang)產(chan)生(sheng)(sheng)較(jiao)小(xiao)的(de)(de)電(dian)(dian)(dian)流(liu)。除此之外,光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)的(de)(de)噪聲(sheng)較(jiao)小(xiao)。雪崩光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)具(ju)有類(lei)似(si)的(de)(de)預(yu)先布(bu)置,但通常在更大(da)的(de)(de)反向(xiang)(xiang)(xiang)偏(pian)(pian)(pian)置下運行(xing)。這(zhe)樣一來,每個由(you)光(guang)(guang)(guang)(guang)產(chan)生(sheng)(sheng)的(de)(de)提供者就(jiu)可以與(yu)雪崩擊穿次(ci)數相(xiang)乘,從而導致光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)二極管(guan)(guan)(guan)(guan)的(de)(de)內部效應,并提高(gao)器件的(de)(de)整體(ti)響應度。
