the Functions of a Diode
May 15, 2018


By using the unidirectional conductivity of the diode, alternating current with alternating direction can be transformed into a single direction pulsative direct current.

2. Switching

The resistance of the diode is very small under the action of the forward voltage, which is in the conduction state, and it is equivalent to a connected switch. Under the action of the reverse voltage, the resistance is very large and is in the cut-off state, like a disconnected switch. By using the switching characteristics of diodes, various logic circuits can be made.
