瞬态***二极管是用来保护输入/输出接口、Vcc总线以及电信设备、计算机、工业设备和消费电子产品中的易损电路，使其免受雷击、感应负载开关和静电放电（ESD）等产生的高压瞬态电流的损害。瞬态***二极管封装类型有两种：表面贴装型和轴向引线型;瞬态***（TVS）二极管***AJ、***BJ、***CJ、SOD-323、SOT-23，SOD-123系列。==================================================================================UniBiUniBiVRWM(V)VBR≦(V)VBR≧(V)IT(mA)VC(V)1.5KE68A1.5KE68CA58.164.6071.40192.0016.3051.5KE75A1.5KE75CA64.171.2578.751103.014.5651.5KE82A1.5KE82CA70.177.9086.101113.013.2751.5KE91A1.5KE91CA77.886.4595.551125.012.0051.5KE100A1.5KE100CA85.595.00105.001137.010.9551.5KE110A1.5KE110CA94.0104.50115.501152.09.8751.5KE120A1.5KE120CA102.0114.00126.001165.09.0951.5KE130A1.5KE130CA111.0123.50136.501179.08.3851.5KE150A1.5KE150CA128.0142.50157.501207.07.2551.5KE160A1.5KE160CA136.0152.00168.001219.06.8551.5KE170A1.5KE170CA145.0161.50178.501234.06.4151.5KE180A1.5KE180CA154.0171.00189.001246.06.1051.5KE200A1.5KE200CA171.0190.00210.001274.05.4751.5KE220A1.5KE220CA185.0209.00231.001328.04.5751.5KE250A1.5KE250CA214.0237.50262.501344.04.3651.5KE300A1.5KE300CA256.0285.00315.001414.03.6251.5KE350A1.5KE350CA299.3332.50367.501482.03.1151.5KE380A1.5KE380CA324.9361.00399.001524.42.8651.5KE400A1.5KE400CA324.0380.00420.001552.02.7251.5KE440A1.5KE440CA376.2418.00462.001607.22.475-----------------------------------------------------------------------------------------------瞬态***二极管选型要点：1.TVS的击穿电压要高于用户的正常工作电压，并留有一定的余量。2.根据不同的应用接口选择使用双向还是单向的TVS。直流电源接口一般使用单向的TVS。交流电源接口和通信接口一般使用双向的TVS。3.根据要过的浪涌等级来选择不同功率的TVS-----------------------------------------------------------------------------------------------储存条件.1储存温度：-10℃～+40℃；.2储存湿度：≤75%RH；3避免存放在具有腐蚀性气体及光照直射的环境下；4包装打开后需重新密封保存；5储存期限：壹年备注：储存条件相当重要，否则有出现氧化的可能)
