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?
, \1 ]# v3 {) @/ C- E' RSwitching 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.

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
