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?
7 l) ^4 z1 }: W$ \- o/ @! \3 CSwitching 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.

Switching Diodes
Switching diodes have lower power ratings than rectifier diodes, but can function better in high frequency application and in clipping and clamping operations that deal with short-duration pulse waveforms;
