Key Concepts

Threshold Voltage

The threshold voltage is the minimum voltage necessary to overcome the potential barrier of a diode's p-n junction. In the forward biased condition, once the applied voltage exceeds this threshold, the diode begins to conduct appreciable current, exhibiting low resistance to the flow of charge.

Diode

A diode is a semiconductor device that allows current to flow in one direction while blocking it in the reverse direction. Its fundamental operation is based on the p-n junction, which creates a built-in potential barrier that must be overcome for current conduction to occur.

Forward Bias

Forward biasing a diode involves applying a voltage across the diode in the direction that reduces the built-in potential barrier. This enables charge carriers to cross the junction, allowing current to flow through the diode once a certain minimum voltage, called the threshold or cut-in voltage, is exceeded.
