Implementation of the Switching Function of Switching Diodes

The switching function of a switching diode is achieved by utilizing the unidirectional conductivity characteristics of the diode. When a forward bias is applied to the diode, it is in a conduction state, and when a reverse bias is applied, it is in a cut-off state, playing a role in turning on and off the current in the circuit. Namely, the switch function.

To improve the switching characteristics of the diode, a manufacturing process can be used to reduce its forward resistance and increase its reverse resistance, in order to improve its switching speed.

Switching Diodes have an important parameter, reverse recovery time. It refers to the time required for the switching diode to transition from conduction to cutoff. The shorter the time, the better. In addition, the time required for Switching Diodes from cut-off to conduction is called the turn-on time. The sum of the activation time and reverse recovery time is called the switching time. Since the reverse recovery time is much greater than the activation time, the general parameter manual only provides the reverse recovery time.

Because the Switching Diodes has the characteristics of fast switching speed, long life, contactless, small size, high reliability, etc., it is widely used in various automatic control circuits, communication circuits, instrument circuits, Home computer circuits, TV sets, DVD players, video recorders and other circuits.
