苏州创芯奇半导体有限公司 电压测方法 可控硅为什么其有“以小控大”的可控性呢？下面我们用图表-27来简单分析可控硅的工作原理。 首先，可以把从阴极向上数的**、二、三层看面是一只NPN型号晶体管，而二、三四层组成另一只PNP型晶体管。其中第二、*三层为两管交迭共用。当在阳极和阴极之间加上一个，又在控制较G和之间（相当BG1的基一射间）输入一个正的触发信号，BG1将产生电流Ib1，经放大，BG1将有一个放大了β1倍的电流IC1。因为BG1集电极与BG2基较相连，IC1又是BG2的基较电流Ib2。BG2又把比Ib2（Ib1）放大了β2的集电极电流IC2送回BG1的基较放大。如此循环放大，直到BG1、BG2完全导通。实际这一过程是“一触即发”的过程，对可控硅来说，触发信号加入，可控硅立即导通。导通的时间主要决定于可控硅的性能。 优势代理产品为大功 率平板式晶闸管、可控硅、二极管、IGBT， 品牌 如EUPEC、西 门康、西码 、三菱、ABB、三社、IR、 明纬开关电源等国外功率模块。 在国 内严格按照国际标准生产：ZP型普通整流管、ZK型 快速整流管、KP型普通晶闸管、 KS型双向晶闸管、KK型快 速晶闸管、KG型高 频 晶闸 管、桥式整流器、电力模块、肖特基模块、 SF**快恢复二极管、电焊 机**模块、固态继电器、固态调压器、型材散热器等电力半导体器件。 本公司坚持以‘诚信为本、质量**、价格合理’的经营理念 期待与贵公司的合作，一步一个脚印，做大做强，再创辉煌！ N275SH08 N282SH20 N282SH22 N281SH12 N281SH14 N281SH16 N281SH18 N280SH02 N280SH04 N280SH06 N280SH08 N280SH10 N280SH12 N280SH14 N280SH16 N310SH02 N310SH04 N310SH06 N255SH36 N255SH38 N255SH40 N255SH42 N255SH44 N255SH45 N260SH02 N260SH04 N260SH06 N260SH08 N260SH10 N260SH12 N260SH14 N260SH16 N260SH18 N260SH20 N260SH22 N260SH24 N260SH26 N260SH28 N260SH30 N260SH32 N260SH34 N260SH36 N330SH16 N330SH18 N330SH20 N330SH22 N330SH24 N330SH26 N350SH02 N350SH04 N350SH06 N350SH08 N350SH10 N350SH12 N350SH14 N350SH16 N350SH18 N370SH02 N370SH04 N370SH06 N370SH08 N370SH10 N370SH12 N370SH14 N370SH16 N370SH18 N520SH02 N520SH04 N520SH06 N520SH08 N520SH10 N520SH12 N520SH14 N520SH15 N320SH36 N320SH38 N320SH40 N320SH42 N320SH44 N320SH45 N360SH22 N360SH24 N360SH26 N360SH28 N360SH30 N360SH32 N360SH34 N360SH36 N360SH38 N390SH22 N390SH24 N390SH26 N390SH28 N390SH30 N390SH32 N390SH34 N390SH36 N390SH38 N450SH14 N450SH16 N450SH18 N450SH20 N450SH22 N450SH24 N450SH26 N490SH02 N490SH04 N490SH06 N490SH08 N490SH10 N490SH12 N490SH14 N490SH16 N490SH18 N490SH20 N490SH22 N490SH24 N490SH26 N510SH02 N510SH04 N510SH06 N510SH08 N510SH10 N510SH12 N510SH14 N510SH16 N510SH18 N510SH20 ?
