固体放电管为多层PN结构成的可控硅结构，因此具有响应速度快，导通电压低，通态压降低，通流能量大，无老化失效，无极性双向保护，产品一致性及稳定性远优于气体放电管及压敏电阻等特点。特别适用于网络通讯设备的精细保护。参数对照表:型号断态电压VDRM(v)max转折电压Vs(v)max通态压降VT(v)max维持电流IH(A)min断态电容C(pF)max封装形式P0080EA/B62555080TO-92P0300EA/B254055080TO-92P0640EA/B5877515050TO-92P0800EA/B7598515050TO-92P1500EA/B140180515030TO-92P1800EA/B160220515030TO-92P2300EA/B290260515030TO-92P2600EA/B220300515030TO-92P3100EA/B275350515030TO-92P3500EA/B320400515030TO-92P0080SA/B62555080DO-214AAP0300SA/B254055080DO-214AAP0640SA/B5877515050DO-214AAP0800SA/B7598515050DO-214AAP1500SA/B140180515030DO-214AAP1800SA/B160220515030DO-214AAP2300SA/B290260515030DO-214AAP2600SA/B220300515030DO-214AAP3100SB/B275350515030DO-214AAP3500SA/B320400515030DO-214AASDT70725872515050SIP3SDT7150120150515040SIP3SDT7180140190515040SIP3SDT7260200260515040SIP3SDT301061555025SO8SDT3021283855025SO8注：1.型号中后缀“A”表示电流等级为50A（10/560us）,“B”为100A。.2.产品在断态电压下流过的***大泄漏电流IDRM不超过5uA.3.电压转折时的***大转换电流IS不超过800mA.4.***大持续通态电流IT不超过1A.5.断态电容是指断态时测的的典型电容值。)
