汽车电子瞬态电压保护在汽车电子网络中，电子控制单元(ECU)通过线束互联，大多数ECU直接或通过启动开关由汽车电池供电。即使在常规操作中也会存在电气干扰和高频影响，通过配线系统传导，***终耦合或以辐射方式干扰到车载电子设备。干扰源包括启动系统、交流电机、负载切换、开关抖动以及“抛负载”(即直流电机运行过程中切断电源，由此产生的电压)。这一浪涌过程可能持续几百毫秒，产生100V以上的电压，对半导体电路具有潜在的致命影响。电源故障情况下的保护瞬态电压***电路，在电路板上滤除低能量脉冲，例如，正、负瞬态电压以及电池瞬间反接导致的尖峰脉冲。这些脉冲通常通过小尺寸的大容值电容、反向保护二级管或者是与瞬态***二极管(TVS)或可变电阻串联的电感进行滤除。TVS二极管雪崩二极管是能够***所有超出其击穿电压的钳位器件。它们能够吸收较高的能量，保护电子电路免遭尖峰电压和抛负载的***。这些二极管具有快速开启、缓慢关断特性。与其它过压保护器件(如：可变电阻)相比，雪崩二极管对过压事件的响应速度更快。其性能指标不会随着使用寿命的延长以及瞬态电压作用次数的增多而降低。在其击穿电压附近，雪崩***二极管具有较大的漏电流。这类二极管通常表示为Transil®、TransZorb®或简称为TVS二极管。常用规格：封装尺寸DiodeCaseStyle:DO-214AB3KW贴片系列：***DJ30A，***DJ30CA，***DJ33A，***DJ33CA，***DJ36A，***DJ36CA，***DJ40A，***DJ40CA5KW贴片系列：5.0***DJ33A5.0***DJ33CA5.0***DJ36A5.0***DJ36CA5.0***DJ40A5.0***DJ40CA5.0***DJ43A5.0***DJ43CA5.0***DJ45A5.0***DJ45CA5.0***DJ48A5.0***DJ48CA5.0***DJ51A5.0***DJ51CA5.0***DJ54A5.0***DJ54CA15000W轴向引线型瞬态***（TVS）二极管-15KPA系列15KPA系列可专门用于保护敏感电子设备，使其免受雷击和其他瞬态电压事件引起的瞬态电压影响。无卤素，且符合RoHS标准典型温度系数ΔVBR=0.1%×VBR@25°CP600包装内有钝化玻璃芯片接点10×1000μs波形时的峰值脉冲功率为15000W，重复频率（工作循环）:0.01%快速的响应时间:从0伏特至VBR***小值通常小于1.0ps出色的箝位能力增量浪涌电阻较低电压高于36V时，标准IR小于2μA15KPA17A15KPA17CA15KPA18A15KPA18CA15KPA20A15KPA20CA15KPA22A15KPA22CA15KPA24A15KPA24CA15KPA26A15KPA26CA15KPA28A15KPA28CA15KPA30A15KPA30CA15KPA33A15KPA33CA15KPA36A15KPA36CA15KPA40A15KPA40CA15KPA43A15KPA43CA15KPA45A15KPA45CA15KPA48A15KPA48CA15KPA51A15KPA51CA15KPA54A15KPA54CA15KPA58A15KPA58CA15KPA60A15KPA60CA15KPA64A15KPA64CA15KPA70A15KPA70CA15KPA75A15KPA75CA15KPA78A15KPA78CA15KPA85A15KPA85CA15KPA90A15KPA90CA15KPA100A15KPA100CA15KPA110A15KPA110CA15KPA120A15KPA120CA15KPA130A15KPA130CA15KPA150A15KPA150CA15KPA160A15KPA160CA15KPA170A15KPA170CA15KPA180A15KPA180CA15KPA200A15KPA200CA15KPA220A15KPA220CA15KPA240A15KPA240CA15KPA260A15KPA260CA15KPA280A15KPA280CA二极管-瞬态电压***器20KPASERIESTVS20KPA20A20KPA20CA20KPA24A20KPA24CA20KPA26A20KPA26CA20KPA28A20KPA28CA20KPA30A20KPA30CA20KPA32A20KPA32CA20KPA34A20KPA34CA20KPA36A20KPA36CA20KPA40A20KPA40CA20KPA44A20KPA44CA20KPA48A20KPA48CA20KPA52A20KPA52CA20KPA56A20KPA56CA20KPA60A20KPA60CA20KPA64A20KPA64CA20KPA68A20KPA68CA20KPA72A20KPA72CA20KPA80A20KPA80CA20KPA88A20KPA88CA20KPA96A20KPA96CA20KPA104A20KPA104CA20KPA112A20KPA112CA20KPA120A20KPA120CA20KPA132A20KPA132CA20KPA144A20KPA144CA20KPA160A20KPA160CA20KPA172A20KPA172CA20KPA180A20KPA180CA20KPA192A20KPA192CA20KPA204A20KPA204CA20KPA216A20KPA216CA20KPA232A20KPA232CA20KPA240A20KPA240CA20KPA256A20KPA256CA20KPA280A20KPA280CA20KPA300A20KPA300CATVS二极管-瞬态电压***二极管器30KPASERIES30KPA28A30KPA28CA30KPA30A30KPA30CA30KPA33A30KPA33CA30KPA36A30KPA36CA30KPA39A30KPA39CA30KPA42A30KPA42CA30KPA43A30KPA43CA30KPA45A30KPA45CA30KPA48A30KPA48CA30KPA51A30KPA51CA30KPA54A30KPA54CA30KPA58A30KPA58CA30KPA60A30KPA60CA30KPA64A30KPA64CA30KPA66A30KPA66CA30KPA70A30KPA70CA30KPA71A30KPA71CA30KPA72A30KPA72CA30KPA75A30KPA75CA30KPA78A30KPA78CA30KPA84A30KPA84CA30KPA90A30KPA90CA30KPA96A30KPA96CA30KPA102A30KPA102CA30KPA108A30KPA108CA30KPA120A30KPA120CA30KPA132A30KPA132CA30KPA144A30KPA144CA30KPA150A30KPA150CA30KPA156A30KPA156CA30KPA160A30KPA160CA30KPA168A30KPA168CA30KPA170A30KPA170CA30KPA180A30KPA180CA30KPA198A30KPA198CA30KPA216A30KPA216CA30KPA240A30KPA240CA30KPA258A30KPA258CA30KPA260A30KPA260CA30KPA270A30KPA270CA30KPA280A30KPA280CA30KPA288A30KPA288CA)
