CDSQR400B-HF Application Field and Working Principle

The CDSQR400B-HF is a single, 400V, 0.1A, general purpose silicon rectifier diode. It is designed for use in applications such as UPS systems, LCD TVs and power supplies. The device has a very fast switching time, low forward voltage drop, and high speed reverse recovery time.

Application Field

The CDSQR400B-HF is mainly used in switched mode power supplies (SMPS) such as UPS systems, LCD TVs, and electronic ballasts. It is also suitable for the protection of switching regulators and other high-frequency circuits. The device has excellent switching performance and reliable operation over a wide range of input and output voltages.

Working Principle

The CDSQR400B-HF is a single silicon rectifier diode that works on a basic principle known as “P-N junction”. This engineering principle is based on the fact that when two dissimilar types of semiconductor material are placed in contact with each other, charge carriers in the form of electron holes are formed. The diode consists of an n-type semiconductor region and a p-type semiconductor region connected together. The n-type region has an excess of electrons while the p-type has an excess of holes. When the diode is forward biased, meaning electrons flow from the n-type to the p-type, current flows and the diode is in its “on” state. When the diode is reverse biased, meaning electrons flow from the p-type to the n-type, current does not flow and the diode is in its “off” state.

The CDSQR400B-HF can also be used in various rectifier applications. It has a low reverse recovery time and a low forward voltage drop which make it suitable for use in power rectification applications. It has a high speed switching which also makes it ideal for use in high frequency switching applications. The device provides high performance in applications where speed and low voltage drop are key factors.
