Working Principle

A rectifier is an electronic component that is used to convert AC voltage into DC voltage. The BYG21K-E3/TR rectifier diode is an example of a single-phase rectifier. It works by allowing current to flow in one direction, while blocking the flow of current in the opposite direction. This action is achieved through the use of an N-channel Si-MOSFET, which allows positive current to flow in one direction, and negative current to be blocked. The efficiency of the device is also enhanced by its low on-state resistance.

Conclusion

The BYG21K-E3/TR rectifier diode is an advanced rectifier component with a wide range of applications in the consumer electronics, automotive and industrial sectors. Its high performance capabilities, combined with its low on-state resistance, make it an ideal choice for use in high power switchmode applications. Its working principle is based on the use of an N-channel Si-MOSFET, which allows current to flow in one direction while blocking the flow in the opposite direction. This allows the device to efficiently convert AC voltage into DC voltage.
