SP3145系列瞬态抑制二极管阵列是LITTELFUSE（力特）推出行业首创的一款单向型、采用01005型封装的ESD保护设备。单向保护性能优于双向保护，对于逻辑和数据线路而言更是如此，这些线路在正常工作中通常不会传输零伏电压。该系列二极管阵列采用快熔型半导体技术，可经受多次ESD事故，同时不会出现磨损或性能减退现象。此外，低标称电容使得这款产品适用于以高数据速率（接近5GHz时钟频率）运行的接口。

SP3145系列的功能与特色：
• 业内首创的单向保护，对于数据线路保护以及不传输零伏电压的接口而言至关重要
• ESD，IEC 61000-4-2，±20kV接触放电，±25kV空气放电
• EFT，IEC 61000-4-4，40A（5/50ns）
• 雷击，IEC61000-4-5第2版，1A（tp=8/20μs）
• VR=0V时的低电容为0.35pF
• 低泄漏电流：2.8V环境下为20nA（最大）
• 业内最小的单通道封装，标称值为01005
• 无卤素，无铅，符合RoHS

SP3145系列的电气特性：

SP3145系列的应用：
• 手机
• 智能电话
• 摄像机
• 便携式医疗设备
• 数码相机
• 可穿戴技术
• 便携式导航设备
• 平板电脑
• 销售点终端机
