人們在(zai)制(zhi)造工(gong)(gong)藝(yi)(yi)和(he)結構上采取了一些改進措施，做(zuo)出(chu)了能(neng)(neng)(neng)適應(ying)于高頻應(ying)用的(de)(de)(de)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)，我們將(jiang)它(ta)稱為快速(su)(su)(su)(su)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)。它(ta)具有以下幾個特點(dian)。一、關(guan)斷時(shi)間(jian)(jian)（toff）短導(dao)(dao)(dao)通(tong)(tong)的(de)(de)(de)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)，當切(qie)斷正(zheng)向電(dian)流(liu)(liu)(liu)時(shi)。并不能(neng)(neng)(neng)馬上“關(guan)斷”，這(zhe)時(shi)如(ru)立即加上正(zheng)向電(dian)壓，它(ta)還會(hui)繼續導(dao)(dao)(dao)通(tong)(tong)。從切(qie)斷正(zheng)向電(dian)流(liu)(liu)(liu)直(zhi)到(dao)控(kong)制(zhi)極恢(hui)復(fu)控(kong)制(zhi)能(neng)(neng)(neng)力需(xu)要的(de)(de)(de)時(shi)間(jian)(jian)，叫做(zuo)關(guan)斷時(shi)間(jian)(jian)。用t0仟表示(shi)。晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)的(de)(de)(de)關(guan)斷過(guo)(guo)程，實際上是儲存(cun)載流(liu)(liu)(liu)子的(de)(de)(de)消(xiao)失過(guo)(guo)程。為了加速(su)(su)(su)(su)這(zhe)種消(xiao)失過(guo)(guo)程，制(zhi)造快速(su)(su)(su)(su)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)時(shi)采用了摻(chan)金工(gong)(gong)藝(yi)(yi)，把(ba)金摻(chan)到(dao)硅(gui)中減少基(ji)區少數(shu)載流(liu)(liu)(liu)子的(de)(de)(de)壽命。硅(gui)中摻(chan)金量越(yue)多(duo)，t0仟越(yue)小(xiao)(xiao)，但摻(chan)金量過(guo)(guo)多(duo)會(hui)影響元件的(de)(de)(de)其(qi)它(ta)性能(neng)(neng)(neng)。二、導(dao)(dao)(dao)通(tong)(tong)速(su)(su)(su)(su)度快．能(neng)(neng)(neng)耐較高的(de)(de)(de)電(dian)流(liu)(liu)(liu)上升率（dI/dt）控(kong)制(zhi)極觸(chu)發(fa)(fa)(fa)(fa)導(dao)(dao)(dao)通(tong)(tong)的(de)(de)(de)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)。總是在(zai)靠近控(kong)制(zhi)極的(de)(de)(de)陰極區域首先導(dao)(dao)(dao)通(tong)(tong)，然后(hou)逐(zhu)漸(jian)向外擴展，直(zhi)到(dao)整個面(mian)(mian)積(ji)導(dao)(dao)(dao)通(tong)(tong)。大面(mian)(mian)積(ji)的(de)(de)(de)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)需(xu)要50～100微秒以上才能(neng)(neng)(neng)積(ji)導(dao)(dao)(dao)通(tong)(tong)。初(chu)始導(dao)(dao)(dao)通(tong)(tong)面(mian)(mian)積(ji)小(xiao)(xiao)時(shi)，必須(xu)限制(zhi)初(chu)始電(dian)流(liu)(liu)(liu)的(de)(de)(de)上升速(su)(su)(su)(su)度，否則將(jiang)發(fa)(fa)(fa)(fa)生(sheng)局部過(guo)(guo)熱現象，影響元件的(de)(de)(de)性能(neng)(neng)(neng)，甚至燒壞。高頻工(gong)(gong)作時(shi)這(zhe)種現象更為嚴(yan)重。為此(ci)，仿造了集成電(dian)路的(de)(de)(de)方(fang)法(fa)，在(zai)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)同一硅(gui)片上做(zuo)出(chu)一個放大觸(chu)發(fa)(fa)(fa)(fa)信號(hao)用的(de)(de)(de)小(xiao)(xiao)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)。控(kong)制(zhi)極觸(chu)發(fa)(fa)(fa)(fa)小(xiao)(xiao)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)后(hou)，小(xiao)(xiao)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)的(de)(de)(de)初(chu)始導(dao)(dao)(dao)通(tong)(tong)電(dian)流(liu)(liu)(liu)將(jiang)橫(heng)向經過(guo)(guo)硅(gui)片流(liu)(liu)(liu)向主(zhu)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)陰極，觸(chu)發(fa)(fa)(fa)(fa)主(zhu)晶(jing)閘(zha)(zha)(zha)管(guan)(guan)(guan)。上海品質DAWIN韓國大衛(wei)模塊工(gong)(gong)廠直(zhi)銷
