场效应(ying)(ying)管(guan)导通(tong)与截止由栅源(yuan)电压来操控，关于(yu)增(zeng)强(qiang)场效应(ying)(ying)管(guan)方面来说，N沟道的管(guan)子加(jia)正向电压即(ji)导通(tong)，P沟道的管(guan)子则加(jia)反向电压。一般2V～4V就OK了(le)。可是(shi)，场效应(ying)(ying)管(guan)分为(wei)增(zeng)强(qiang)型和耗(hao)尽(jin)型，增(zeng)强(qiang)型的管(guan)子是(shi)必(bi)须需(xu)求加(jia)电压才干导通(tong)的，而耗(hao)尽(jin)型管(guan)子本来就处于(yu)导通(tong)状(zhuang)况，加(jia)栅源(yuan)电压是(shi)为(wei)了(le)使其截止。
开(kai)(kai)关只有两种状(zhuang)况(kuang)通和断，三(san)极管和场效应(ying)管作(zuo)业有三(san)种状(zhuang)况(kuang)，1.截(jie)止，2.线(xian)性扩大，3.饱满（基极电(dian)(dian)(dian)流持续添(tian)加(jia)而集电(dian)(dian)(dian)极电(dian)(dian)(dian)流不(bu)再添(tian)加(jia)）。使晶体(ti)管只作(zuo)业在(zai)1和3状(zhuang)况(kuang)的(de)电(dian)(dian)(dian)路称之为开(kai)(kai)关电(dian)(dian)(dian)路，一般以晶体(ti)管截(jie)止，集电(dian)(dian)(dian)极不(bu)吸收电(dian)(dian)(dian)流表(biao)(biao)明(ming)开(kai)(kai)关；以晶体(ti)管饱满，发(fa)射极和集电(dian)(dian)(dian)极之间的(de)电(dian)(dian)(dian)压差挨(ai)(ai)近于(yu)0V时表(biao)(biao)明(ming)开(kai)(kai)。开(kai)(kai)关电(dian)(dian)(dian)路用(yong)于(yu)数字电(dian)(dian)(dian)路时，输出电(dian)(dian)(dian)位(wei)挨(ai)(ai)近0V时表(biao)(biao)明(ming)0，输出电(dian)(dian)(dian)位(wei)挨(ai)(ai)近电(dian)(dian)(dian)源电(dian)(dian)(dian)压时表(biao)(biao)明(ming)1。所以数字集成电(dian)(dian)(dian)路内(nei)部的(de)晶体(ti)管都工作(zuo)在(zai)开(kai)(kai)关状(zhuang)况(kuang)。
场效应管按沟(gou)(gou)道(dao)分可分为(wei)Ｎ沟(gou)(gou)道(dao)和Ｐ沟(gou)(gou)道(dao)管（在(zai)符号图中可看到中间(jian)的(de)箭头(tou)方向不一样）。
按资(zi)料可分为结型(xing)(xing)管(guan)和(he)绝(jue)缘栅型(xing)(xing)管(guan)，绝(jue)缘栅型(xing)(xing)又分为耗尽型(xing)(xing)和(he)增强(qiang)型(xing)(xing)，一(yi)般主板(ban)上大(da)多(duo)是(shi)绝(jue)缘栅型(xing)(xing)管(guan)简称(cheng)(cheng)MOS管(guan)，而且大(da)多(duo)选用增强(qiang)型(xing)(xing)的(de)Ｎ沟道，其次是(shi)增强(qiang)型(xing)(xing)的(de)Ｐ沟道，结型(xing)(xing)管(guan)和(he)耗尽型(xing)(xing)管(guan)简直不用。 场(chang)效(xiao)(xiao)应晶(jing)(jing)体(ti)(ti)管(guan)简称(cheng)(cheng)场(chang)效(xiao)(xiao)应管(guan).由(you)大(da)都载(zai)流子参加导(dao)电,也称(cheng)(cheng)为单(dan)极型(xing)(xing)晶(jing)(jing)体(ti)(ti)管(guan).它归于电压(ya)操(cao)控型(xing)(xing)半导(dao)体(ti)(ti)器材. 场(chang)效(xiao)(xiao)应管(guan)是(shi)使用大(da)都载(zai)流子导(dao)电,所以称(cheng)(cheng)之为单(dan)极型(xing)(xing)器材,而晶(jing)(jing)体(ti)(ti)管(guan)是(shi)即有大(da)都载(zai)流子,也使用少量载(zai)流子导(dao)电,被称(cheng)(cheng)之为双极型(xing)(xing)器材. 有些场(chang)效(xiao)(xiao)应管(guan)的(de)源(yuan)极和(he)漏极能够交换使用,栅压(ya)也可正可负,灵活(huo)性比晶(jing)(jing)体(ti)(ti)管(guan)好。
