【应用】1N4148WS小信号开关二极管用于MOSFET驱动电路，具有高速开关、低正向压降等优势
目前，发光二极管(LED)由于节能、环保、转化效率高、寿命长等众多优点，在照明系统应用中逐渐占据主导地位。LED稳定高效的运行，需要高性能的驱动器为其提供稳定可靠的电源供应。该类驱动器通常采用先进的分立元器件构建，并结合电力电子技术、数字控制技术，构建成基于电压电流反馈的控制系统，为LED提供良好的运行条件。图1所示为采用flyback拓扑结构的LED驱动器。
图1. 采用flyback拓扑结构的LED驱动器
如上图所示，市电经过全桥整流、滤波后为后级变换器提供310V左右直流电压，后级flyback采用MOSFET斩波，并通过输出电压、电流反馈控制，输出标称的LED驱动电压。对于MOSFET驱动电路，通常采用专用的驱动IC和离散器件构成，如图2所示。MCU控制芯片输出的PWM脉宽调制信号通过驱动IC整形放大后，送入后侧电阻、二极管电路，驱动MOSFET的开通、关闭。通常MOSFET处于较高频率的开关状态，需要较短的开通时间和关断时间，其驱动过程等效于向MOSFET栅极输入电容Ciss进行充放电，当MOSFET由开通进入关断状态时，为了加快其关断速度，需要在栅极驱动电阻上并联二极管（图2中D1二极管），便于快速泄放栅极电容电荷，加速MOSFET关断。针对此处的应用，DIOTEC（德欧泰克）推荐1N4148WS小信号开关二极管，该二极管具有非常高的开关速度和较低正向压降，能将栅极输入电容的电荷快速、充分的泄放，加速MOSFET的关闭，其外观、尺寸如图3所示。

图3. IN4148WS封装与尺寸
1N4148WS主要电气参数如下表所示：
1N4148WS小信号开关二极管的最大可承受功耗为200mW，最大结温范围均为-55~150℃，具有很靠的可靠性，最大正向压降VF在IF=10mA,Tj=25℃是仅855mV，低正向压降有利于栅极输入电容电荷充分泄放，提供稳定的关闭状态。
1N4148WS小信号开关二极管无铅并符合RoHS、REACH标准，外壳材料阻燃等级达到UL 94V-0，重量约为0.005g，并提供通过AEC-Q101认证的车载级的版本（部件号带尾缀Q），是一款可靠性高、开关速度快、绿色环保的器件。
