What is a Switching Diode?/ @# R  J' ?3 C3 ?
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.

Applications for Switching Diodes:* t2 Z% C+ ^5 V5 k
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.: n$ H$ u4 D4 p% R$ J) L. e

你的理解是對的啦！它解釋的部分和一般的二級管沒什麼兩樣，真正的差異反而是寫在下面應用（Application）那段。
