瞬態(tài)抑制二極管(TVS)又叫箝位型二極管，是目前國(guó)際上普遍使用的一種能電路保護(hù)器件，它的外型與普通二極管相同，但卻能吸收高達(dá)數(shù)千瓦的浪涌功率。 它的主要特點(diǎn)是在反向應(yīng)用條件下，當(dāng)承受一個(gè)高能量的大脈沖時(shí)，其工作阻抗立即降至極低的導(dǎo)通值，從而允許大電流通過(guò)，同時(shí)把電壓箝制在預(yù)定水平，其響應(yīng)時(shí)間僅為10-12毫秒，因此可有效地保護(hù)電子線路中的精密元器件。 TVS允許的正向浪涌電流在TA＝250C，T＝10ms條件下，可達(dá)50～200A。 雙向TVS可在正反兩個(gè)方向吸收瞬時(shí)大脈沖功率，并把電壓箝制到預(yù)定水平，雙向TVS適用于交流電路，單向TVS一般用于直流電路。可用于防雷擊、防過(guò)電壓、抗干擾、吸收浪涌功率等，是一種理想的保護(hù)器件。 ★瞬態(tài)抑制二級(jí)管（TVS） SMBJ5.0A/CA SMCJ5.0A/CA P6KE6.8A/CA 1.5KE6.8A/CA SMBJ6.0A/CA SMCJ6.0A/CA P6KE7.5A/CA 1.5KE7.5A/CA SMBJ6.5A/CA SMCJ6.5A/CA P6KE8.2A/CA 1.5KE8.2A/CA SMBJ7.0A/CA SMCJ7.0A/CA P6KE9.1A/CA 1.5KE9.1A/CA SMBJ7.5A/CA SMCJ7.5A/CA P6KE10A/CA 1.5KE10A/CA SMBJ8.0A/CA SMCJ8.0A/CA P6KE11A/CA 1.5KE11A/CA SMBJ8.5A/CA SMCJ8.5A/CA P6KE12A/CA 1.5KE12A/CA SMBJ9.0A/CA SMCJ9.0A/CA P6KE13A/CA 1.5KE13A/CA SMBJ10A/CA SMCJ10A/CA P6KE14A/CA 1.5KE14A/CA SMBJ11A/CA SMCJ11A/CA P6KE15A/CA 1.5KE15A/CA SMBJ12A/CA SMCJ12A/CA P6KE16A/CA 1.5KE16A/CA SMBJ13A/CA SMCJ13A/CA P6KE18A/CA 1.5KE18A/CA SMBJ14A/CA SMCJ14A/CA P6KE20A/CA 1.5KE20A/CA SMBJ15A/CA SMCJ15A/CA P6KE22A/CA 1.5KE22A/CA SMBJ16A/CA SMCJ16A/CA P6KE24A/CA 1.5KE24A/CA SMBJ17A/CA SMCJ17A/CA P6KE27A/CA 1.5KE27A/CA SMBJ18A/CA SMCJ18A/CA P6KE30A/CA 1.5KE30A/CA SMBJ20A/CA SMCJ20A/CA P6KE33A/CA 1.5KE33A/CA SMBJ22A/CA SMCJ22A/CA P6KE36A/CA 1.5KE36A/CA SMBJ24A/CA SMCJ24A/CA P6KE39A/CA 1.5KE39A/CA SMBJ26A/CA SMCJ26A/CA P6KE43A/CA 1.5KE43A/CA SMBJ28A/CA SMCJ28A/CA P6KE47A/CA 1.5KE47A/CA SMBJ30A/CA SMCJ30A/CA P6KE51A/CA 1.5KE51A/CA SMBJ33A/CA SMCJ33A/CA P6KE56A/CA 1.5KE56A/CA SMBJ36A/CA SMCJ36A/CA P6KE62A/CA 1.5KE62A/CA SMBJ40A/CA SMCJ40A/CA P6KE68A/CA 1.5KE68A/CA SMBJ43A/CA SMCJ43A/CA P6KE75A/CA 1.5KE75A/CA SMBJ45ACA SMCJ45ACA P6KE82A/CA 1.5KE82A/CA SMBJ48A/CA SMCJ48A/CA P6KE91A/CA 1.5KE91A/CA SMBJ51A/CA SMCJ51A/CA P6KE100A/CA 1.5KE100A/CA SMBJ54A/CA SMCJ54A/CA P6KE110A/CA 1.5KE110A/CA SMBJ58A/CA SMCJ58A/CA P6KE120A/CA 1.5KE120A/CA SMBJ60A/CA SMCJ60A/CA P6KE130A/CA 1.5KE130A/CA SMBJ64A/CA SMCJ64A/CA P6KE140A/CA 1.5KE140A/CA SMBJ70A/CA SMCJ70A/CA P6KE150A/CA 1.5KE150A/CA SMBJ75A/CA SMCJ75A/CA P6KE160A/CA 1.5KE160A/CA SMBJ78A/CA SMCJ78A/CA P6KE170A/CA 1.5KE170A/CA SMBJ85A/CA SMCJ85A/CA P6KE180A/CA 1.5KE180A/CA SMBJ90A/CA SMCJ90A/CA P6KE200A/CA 1.5KE200A/CA SMBJ100A/CA SMCJ100A/CA P6KE220A/CA 1.5KE220A/CA SMBJ110A/CA SMCJ110A/CA P6KE250A/CA 1.5KE250A/CA SMBJ120A/CA SMCJ120A/CA P6KE300A/CA 1.5KE300A/CA SMBJ130A/CA SMCJ130A/CA P6KE350A/CA 1.5KE350A/CA SMBJ140A/CA SMCJ140A/CA P6KE400A/CA 1.5KE400A/CA SMBJ150A/CA SMCJ150A/CA P6KE440A/CA 1.5KE440A/CA SMBJ160A/CA SMCJ160A/CA SMBJ170A/CA SMCJ170A/CA 還有：5KPXXX 系列，15KPAXXX系列；20KPAXXX系列；30KPAXXX系列。
