Diodes and it's characteristics A diode is a semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. It consists of a PN junction, which is formed by joining p-type (positive) and n- type (negative) semiconductor materials. Working Principle of a Diode Forward Bias (Conducting Mode) When the positive terminal of a power supply is connected to the p-side and the negative terminal to the n-side, the diode is said to be in forward bias. This reduces the depletion region (a barrier at the junction) and allows current to flow easily. A small voltage (typically 0.7V for silicon and 0.3V for germanium) is required to start conduction. Reverse Bias (Blocking Mode)
