What is a Switching Diode?
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.
Types of Switching Diodes:
There are many different kinds of switching diodes. At Topdiode, we supply many of the most common types categorized by power dissipation, maximum reverse recovery time, maximum reverse voltage, maximum average forward current, packaging type and maximum peak current. The most common values for power dissipation are 200 mW, 250 mW, 350 mW and 500 mW. Please refer to our products page.
Applications for Switching Diodes:
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.
