Different types of diodes and their properties: Two terminal Junction Diodes: A p-n junction diode is a solid-state device that has two terminals. Depending on impurity distribution, device geometry, and biasing condition, a junction diode can perform various functions. There are a very large variety of diodes with voltage ratings from <1V to >2000V and current ratings from <1mA to >5000A. P-N junctions can generate and detect light and convert optical radiation into electrical energy. Rectifier: This type of p-n junction diode is specifically designed to rectify an alternating current i.e. to give a low resistance to current flow in one direction and a very high resistance in the other direction. Such diodes are generally designed for use as power- rectifying devices that operate at frequencies from 50 – 50K Hz. The majority of rectifiers have power-dissipation capabilities from 0.1 to 10 watts and a reverse breakdown ...
