肖特基二极管的用途有哪些?
肖特基二极管是一种低功耗、超高速、反向恢复时间短的二极管。因此,肖特基二极管有许多用途,如高频、低压、大电流整流二极管、续流二极管、保护二极管、整流二极管、小信号检测二极管等。在微波通信和其他电路中。一般来说,肖特基二极管常用于通信电源、变频器等。常用的包装形式有:TO-220AB、ITO-220AB、TO-247。有许多类型的贴片肖特基二极管以SS开头命名的较多。

【应用】正向压降仅0.24V的肖特基二极管BAT54C用于非接触式电子体温计,正向连续电流可达200mA
在非接触式电子体温计的设计中,体温计的实时测量需要RTC提供精准的计时时钟进行同步处理。为了保证系统掉电后时间信息不丢失,RTC一般采用双电源供电。在这种双电源供电路径中,通常采用肖特基二极管作电源隔离,本文推荐使用长晶科技的肖特基二极管BAT54C。
