[ Detailed Data ]

The voltage at which the diode begins to conduct is known as the "forward threshold voltage," and is typically around 0.7 volts for a standard silicon diode. They are also used as protective devices in electronic circuits, to protect sensitive components from overvoltage or reverse voltage.
