封装
注：
1、封装体积较小，正面印字仅有代号而不含全部型号，例如CH412Z代号是12。
2、盘装，每盘整包装数量为3000只，可以零售，但是零售时不会逐个清点数量。
3、型号CH412A不再推荐，但是可以持续供货。
4、型号CH412B已经停产，请换用CH412K，多出的两个通道可以悬空或并联（低速时）
引脚
应用说明
CH412设计用来与被保护芯片内置的ESD保护一起工作。在电气连接方面，CH412的ESD保护通道必须与被保护芯片的I/O引脚以低阻抗并联；在物理布局方面，可以将被保护芯片放置于CH412之后，使得来自外部的ESD冲击首先经过CH412，以保护后面的芯片，但CH412与外部接口的端口连接器之间的连接线不宜过短，较长的连接线可以适当缓和来自外部的ESD冲击。
在PCB电路板设计方面，CH412的GND引脚必须以尽可能低的交直流阻抗连接到全局地（宽线条、多过孔VIA、全铺铜）；对于CH412K，必须在尽可能靠近VCC引脚的地方放置一个0.1μF陶瓷旁路电容，电容的另一端必须以尽可能低的阻抗与全局地连接。
对于IEC61000-4-2规定的HBM人体模型的静电冲击，CH412可以将ESD电流导引到VCC或GND，并将ESD冲击时的峰值电压幅度限制在±25V以下；对于接触放电，峰值电压被限制在±65V；对于气隙放电，峰值电压被限制在±100V。被保护的芯片必须能够承受上述峰值电压，部分芯片有可能会意外复位。考虑到ESD冲击过程中的瞬时峰值电流在40A左右，该峰值电流经由长度约0.5英寸的PCB走线，将因为寄生电感而产生400V的压降，导致实际峰值电压超出预期。良好的布局和走线可以降低地线和电源线以及受保护信号线上的寄生串联电感，降低ESD冲击过程中的峰值电压。
CH412K具有4路ESD保护，可以用于保护4路高速信号或者2对高速差分信号，未用到的ESD保护通道可以悬空或者接地，对于中低速信号还可以两通道并联使用增强保护效果。CH412Z具有4路ESD保护，可以用于保护4路中低速信号或者两对中低速差分信号，未用到的ESD保护通道可以悬空或者接地。CH412Z的寄生电容较大，不宜多通道并联。
绝对最大值
（临界或者超过绝对最大值将可能导致芯片工作不正常甚至损坏）
电气参数
（测试条件：TA=25℃，VCC=5V）
应用
CH412K 应用（下图）
CH412K可以用于USB高速信号的ESD保护，GND直接连接到全局地，VCC连接到3.3V电源电压，并且由电容C4提供电源旁路。来自USB端口P4的信号经由扼流电感或者数欧姆电阻（可选）首先连接到CH412K，接着再连接到USB芯片。未用到的通道可以悬空，对于中低速信号还可以两通道并联以增强保护效果。
CH412Z 应用（下图）
CH412Z可以用于中低频普通信号的ESD保护，也可以用于全速或者低速USB信号的ESD保护。图中CH412Z用于保护CH374U的两个USB-Host端口。
封装信息
下图是SOT363封装尺寸。
SOT353仅比SOT363减少一个引脚（去掉原5#，原6#作为SOT353新5#），其它同SOT363。

【应用】沁恒USB转串口芯片CH340N在便携式低功耗产品上的应用，外围器件少且成本低
作者开发低功耗便携式产品，在前期的开发验证过程中需要用到串口输出调试信息，沁恒科技推出的一款USB转串口芯片CH340N采用SOP-8的封装形式尺寸小，而且成本低满足设计要求。
