整流二极管和一般开关二极管有什么不同？
Both rectifier diodes and typical switching diodes are pn junction diodes. Although they are manufactured in almost the same manner, they are designed for different applications. Rectifier diodes have a forward current of 0.5 A or higher and are designed to convert alternating current (AC) from a mains supply to direct current (DC). In contrast, switching diodes are intended to be used for high-frequency applications (up to 1 MHz), diode logic, weak signal detection, diode clipping, etc.
整流二极管的正向电流是0.5A或更高，设计用于将交流电源线的交流电（AC）转换为直流电（DC）。
