标题: 这种元件的用法
这种二极管的好像用的比较少，平时不怎么用，谁能说下具体用途和可以实现哪些电路功能

What is a Switching Diode?) [+ T# f5 ~! @; F; U: q
Switching diodes are a single p-n diode in a discrete package. A switching diode provides the same functionality as a switch. It has high resistance below the specified applied voltage similar to an open switch, whereas above that voltage it changes in a sudden way to the low resistance of a closed switch. Switching diodes are used in devices such as ring modulation.

The switching diode is the most basic function of almost every electronic application. Switching diodes are also used in high-speed rectifying applications, such as in radiofrequency receivers. Applications also include high-speed switching, general-purpose switching and reverse polarity protection in the consumer, automotive, and telecommunication industry.

我的理解是跟普通二极管一样，只是反向恢复时间较短，是这样吗？你的英文好像是达到一定电压导通，否则，不导通。可是二极管正向也就0.7V左右啊& B) f! J! V% P( H; F
