CDBV3-70-G

Diodes are semiconductor components used to allow the current to flow in one direction only, while blocking the current in the reverse direction. While various diodes perform a wide range of different electrical functions, rectifier diodes form an essential component of many power supplies and are used extensively to convert Alternating Current (AC) to Direct Current (DC). The CDBV3-70-G is a single-phase, MOS field effect rectifier, designed for use in AC/DC current and voltage applications.

Applications

The CDBV3-70-G rectifier is mainly used in commercial and industrial buildings, where it provides reliable AC to DC current and voltage conversion. Due to its high frequency of operation and low input capacitance, the CDBV3-70-G is ideal for high-power applications such as variable speed drives, freezers, and motors. Additionally, it is well-suited for high-speed switching applications due to its low forward voltage drop, fast reverse recovery time, and low thermal resistance. The CDBV3-70-G is also useful in telecommunication and computing equipment, where it is capable of supplying regulated voltage with minimal ripple.

Working Principle

The CDBV3-70-G rectifier is based on the principle of field effect. Essentially, when the rectifier is forward biased, its drain-source resistance is reduced and current started to flow through the rectifier. On the other hand, when the rectifier is reverse biased, high drain-source voltage exists and the reverse current through the MOS will be blocked. This high voltage is used to create a field that regulates the channel of the MOS, thereby preventing the current from flowing in the wrong direction. Additionally, the CDBV3-70-G rectifier is designed with a fast reverse recovery time and low input capacitance, which further enhances the effectiveness of its field effect operation.

Conclusion

The CDBV3-70-G rectifier is used in many different applications to provide reliable AC to DC conversion, and its fast reverse recovery time and low input capacitance make it suitable for high-speed switching applications. Additionally, its field-effect design allows it to effectively regulate the channel of the MOS while also blocking the reverse current flow, making it a reliable and efficient rectifier for commercial and industrial buildings.
