發光二(er)(er)極(ji)(ji)(ji)管(guan)(guan)在我(wo)們生活中(zhong)是比(bi)較常(chang)見的(de)(de)，比(bi)如(ru)說：商(shang)業的(de)(de)走字燈，交(jiao)通燈，LED屏(ping)幕(mu)，LED燈泡(pao)等等。二(er)(er)極(ji)(ji)(ji)管(guan)(guan)是一(yi)(yi)種用(yong)鍺或(huo)者硅半導(dao)體(ti)(ti)材料(liao)做(zuo)成的(de)(de)，半導(dao)體(ti)(ti)材料(liao)導(dao)電(dian)性(xing)能在常(chang)溫(wen)下介于(yu)導(dao)體(ti)(ti)和絕緣體(ti)(ti)之間，一(yi)(yi)百(bai)多(duo)年前就有這個東(dong)西了(le)，是半導(dao)體(ti)(ti)器(qi)(qi)件家族中(zhong)的(de)(de)元(yuan)老了(le)。發光二(er)(er)極(ji)(ji)(ji)管(guan)(guan)只是二(er)(er)極(ji)(ji)(ji)管(guan)(guan)其中(zhong)之一(yi)(yi)，還有許多(duo)不同(tong)用(yong)途的(de)(de)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)：整流(liu)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)、穩壓二(er)(er)極(ji)(ji)(ji)管(guan)(guan)、光電(dian)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)、開關(guan)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)等。整流(liu)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)在我(wo)們生活中(zhong)比(bi)較常(chang)見，都用(yong)在交(jiao)流(liu)轉直流(liu)的(de)(de)電(dian)路中(zhong)：手機充(chong)電(dian)器(qi)(qi)，電(dian)腦充(chong)電(dian)器(qi)(qi)，電(dian)動車充(chong)電(dian)器(qi)(qi)等等。東(dong)莞晶體(ti)(ti)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)出廠價環形調制(zhi)專門(men)用(yong)的(de)(de)二(er)(er)極(ji)(ji)(ji)管(guan)(guan)就是正向特(te)性(xing)一(yi)(yi)致性(xing)好的(de)(de)四個二(er)(er)極(ji)(ji)(ji)管(guan)(guan)的(de)(de)組合件。
二極管(guan)是十(shi)分常用的(de)(de)基(ji)礎(chu)元器件。在(zai)(zai)主回路中，串(chuan)聯一(yi)(yi)(yi)個(ge)二極管(guan)，是利用二極管(guan)的(de)(de)單向導(dao)(dao)電(dian)(dian)的(de)(de)特(te)性(xing)，實(shi)現了(le)較簡單可(ke)靠的(de)(de)低(di)成(cheng)本(ben)防(fang)反(fan)(fan)接功能(neng)電(dian)(dian)路。這(zhe)種低(di)成(cheng)本(ben)方(fang)案一(yi)(yi)(yi)般(ban)在(zai)(zai)小電(dian)(dian)流(liu)的(de)(de)場合，類似小玩具等。因(yin)為二極管(guan)導(dao)(dao)通(tong)(tong)會(hui)有一(yi)(yi)(yi)個(ge)0.7V（硅管(guan)）的(de)(de)導(dao)(dao)通(tong)(tong)壓降，如(ru)果實(shi)際電(dian)(dian)流(liu)很大(da)的(de)(de)話，那么就會(hui)產生一(yi)(yi)(yi)個(ge)熱(re)損耗，會(hui)導(dao)(dao)致發熱(re)。而且(qie)如(ru)果反(fan)(fan)接的(de)(de)電(dian)(dian)壓很大(da)的(de)(de)話，超過反(fan)(fan)向截止電(dian)(dian)壓，也會(hui)擊穿(chuan)二極管(guan)本(ben)身，導(dao)(dao)致二極管(guan)失效，起(qi)不(bu)到防(fang)反(fan)(fan)接的(de)(de)功能(neng)，從而不(bu)能(neng)起(qi)到保(bao)護后級電(dian)(dian)路的(de)(de)作(zuo)用了(le)。
肖特基(ji)(ji)二(er)極管（SchottkyBarrierDiode）它(ta)是(shi)具有肖特基(ji)(ji)特性(xing)的"金屬半(ban)導(dao)體結"的二(er)極管。其(qi)(qi)正向(xiang)起始電壓較(jiao)低。其(qi)(qi)金屬層(ceng)除材(cai)(cai)料外，還可(ke)(ke)以采用金、鉬、鎳、鈦等(deng)材(cai)(cai)料。其(qi)(qi)半(ban)導(dao)體材(cai)(cai)料采用硅或(huo)砷(shen)化鎵，多為N型半(ban)導(dao)體。這種器件(jian)是(shi)由多數載流子導(dao)電的，所以，其(qi)(qi)反向(xiang)飽和電流較(jiao)以少數載流子導(dao)電的PN結大(da)得多。由于肖特基(ji)(ji)二(er)極管中少數載流子的存貯效應甚微，所以其(qi)(qi)頻(pin)率響只為RC時(shi)間常數限制(zhi)(zhi)，因而，它(ta)是(shi)高(gao)頻(pin)和快(kuai)速開關的理想器件(jian)。其(qi)(qi)工(gong)作頻(pin)率可(ke)(ke)達100GHz。并且，MIS（金屬－絕緣體－半(ban)導(dao)體）肖特基(ji)(ji)二(er)極管則(ze)可(ke)(ke)以用來制(zhi)(zhi)作太陽能電池或(huo)發光二(er)極管。在(zai)規(gui)定(ding)散熱條件(jian)下，二(er)極管使(shi)用中不要超過二(er)極管比較(jiao)大(da)整流電流值(zhi)。
