【应用】最大频率小于30kHz时,声频输入/输出信号线避免ESD损害方案
音频信号的最大值为12Vp-p,最大频率小于30kHz。 在该频率下,不需要考虑抑制器的电容量。 需避免受到ESD影响的信号线包括左、右通道。
如下图所示,可使用LITTELFUSE推出的分立式多层压敏电阻V14MLA0402,以便灵活布局。 由于音频信号具有模拟属性,因此建议仅在信号负值为-0.5V或更小时使用单级瞬态抑制二极管阵列SP1001-02XTG,因为它们可在量值较大时削减音频信号的该部分值。
方案一中使用的离散型多层压敏电阻V14MLA0402采用了无引线、表面贴装技术,用于抑制各种瞬态事件,包括IEC 6100-4-2规定的或其他用于电磁兼容性(EMC)标准的瞬态事件。 它可在比齐纳二极管更广泛的温度范围下工作,并有比塑料组件布局更小的封装尺寸(0402)。
方案二中使用单级瞬态抑制二极管阵列SP1001-02XTG每次输入/输出的电容为8pF (TYP),±15kV接触放电、±30kV空气放电的ESD保护(4级、IEC61000-4-2)。电压5V时的(最大)低泄漏电流为0.5μA,小型封装可节省面板空间。符合AEC-Q101标准,其非常低的负载电容也使得它们成为保护高速信号管脚的理想之选,适合用于汽车应用。
除了上述建议外,Littelfuse的MLV产品组合还提供其它解决方案。 例如,如果制造工艺无法处理0402规格的元件,可选用具有同等属性的0603规格的器件。IEC 61000-4-2是最适合此接口的标准规范。 通过该测试可证明终端产品不易受到ESD危害。

【应用】离散型多层压敏电阻V9MLA0402在视频输入/输出中预防ESD侵害方案
用于超级视频和复合视频格式中的视频信号通常会在0.5至2.0Vp-p之间变化,最高频率可达5MHz。建议使用Littelfuse推出的离散型多层压敏电阻V9MLA0402进行保护。 鉴于视频信号所具有的模拟特性,不建议使用单极瞬态抑制二极管阵列,因为这样可能会切断视频信号中的负极性部分。

瞬态抑制二极管(TVS)SP1001漏电流参数的意义是什么?
瞬态电压抑制二极管的漏电流是指PN结间在截止状态下流过的微弱电流,PN结上的漏电流是不可能避免的,因为PN结间只要有电子的存在就不可避免的会做无规则的运动,因而产生漏电流。
