VJ647M - Bridge Rectifiers

VJ647M is a bridge rectifier diode that is popularly used in consumer electronics and various other electronic applications. It is a high voltage, high current device which operates with a wide range of voltages and currents. It is one of the most commonly used types of rectifiers due to its high performance, affordability, and efficiency. In this article, we will discuss the application field and working principle of the VJ647M bridge rectifier diode.

Applications of VJ647M

VJ647M bridge rectifier diodes are mainly used for converting alternating current (AC) to direct current (DC). This is known as rectification. This type of diode is used in a wide variety of consumer electronics including power supplies, laptops, and mobile phones. It is also used in lighting fixtures and industrial equipment such as signal switches and motor controllers. Additionally, the VJ647M bridge rectifier diode is used to provide a constant current source in applications such as rechargeable batteries and solar cells.

Working Principle of VJ647M

A bridge rectifier diode, such as the VJ647M, is a four-terminal semiconductor device consisting of two p-type and two n-type diodes connected together in an opposing configuration. When an AC voltage source is connected to the two input terminals of the bridge rectifier diode, the diode conducts in one direction only and rectifies the alternating current to direct current (DC). The voltage applied to the input terminals appears across the output terminals of the bridge rectifier diode and the current flows through the load connected to the output terminals.

A bridge rectifier diode acts as a two-way switch, where the current is allowed to flow only in one direction, depending on the polarity of the applied voltage. When the voltage applied to the input terminals is positive, the diode conducts in one direction and the current flows through the load connected to the output terminals. Conversely, when the voltage applied to the input terminals is negative, the diode conducts in the opposite direction and the current does not flow to the load.

The VJ647M bridge rectifier diode also performs power factor correction by providing a constant voltage in the load, making it suitable for use in power supplies. While it is not widely used for high power applications, it is suitable for applications that require moderate to low power.

Conclusion

In conclusion, the VJ647M bridge rectifier diode is widely used in various electronic applications due to its high performance, affordability and efficiency. It is mainly used for converting AC to DC, power factor correction, and providing a constant current source in applications such as rechargeable batteries and solar cells. Despite being unable to be used in high power applications, the VJ647M bridge rectifier diode can handle a wide range of voltages and currents and provides a stable source of power regardless of the polarity of the applied voltage.
