Rectifiers Diodes / Schottky Diodes
Rectifiers diodes are electronic devices that allow current to flow in only one direction. They act as a one-way valve and are used to convert alternating current (AC) to direct current (DC). The difference between a standard diodes and a rectifier is that a rectifier is usually rated at a breakdown voltage greater than 50V and has a power rating greater than 1W.
Diodes are used in wide applications in communication systems, computers, radar circuits, radios, and television. Rectifiers diodes are normally found serving as components of DC power supplies and high-voltage direct current power transmission systems. They are also applied in electronic circuit design.
Normal (P/N) diodes is formed by combining P-type and N-type semiconductors together in close contact. Schottky barrier diodes are constructed from metal to form a semiconductor contact. As the metal and semiconductor are brought together, a layer of potential barrier (Schottky Barrier) is formed on the connecting surface which has shown the identity of rectification.
Due schottky barrier diodes with a low forward voltage drop and a very fast switching action, schottky diodes is an ideal diodes. It is popularly used in supplementary interchange power. Therefore, it has been broadly applied in switched power supplies used in electronic circuits, positioning and wave carrier networks, calculation gates, mixed frequency and wave detecting networks and loop protection, etc.
In particular it is used in areas including:
- RF mixer and detector diodes
- Power rectifier
- Power OR circuits
- Solar cell applications
- Clamp diode - especially with its use in LS TTL
