Today in the electronics world, BYG20D R3G is one of the most commonly used single diodes or rectifiers. As a reliable component, it has become broadly applied in various electronic fields due to its wide ranging value, low price, high efficiency, compatibility and safety features. This article will discuss the application fields and working principle of BYG20D R3G.

Application Field

BYG20D R3G can be found in units ranging from the small-scale to the heavyweight power supply. When applied in a rectifier, it plays a critical role in rectifying and stabilizing AC voltage, then providing stable DC voltage for other power circuits. By using this component in power supply, it can help to reduce the thermal noise and improve the output efficiency. Apart from being used in power supply, it also serves as a voltage-controlled switch in motor control, with its ability to regulate the voltage input from the power supply.

Additionally, BYG20D R3G could be used in high frequency oscillator, inverters and voltage converter. In an oscillator, the diodes can block the unidirectional current and stimulate the resonance of the elecronic components, constructing a high frequency oscillatory circuit. Likewise, the rectifiers are also popularly applied in the design of DC-AC inverter and voltage converter, aiming to effectively regulate the voltage.

Working Principle

BYG20D R3G works as a simple switch, closing or opening at certain voltage levels. It allows the current to pass in only one direction while blocking the reverse one. This feature is made possible by the global distribution of negatively charged electron on the n-type semiconductor and the positively charged hole on the p-type semiconductor. Between the electrodes, the function of the holed on the n-type semiconductor is similar to the cathode of the diode, and the electron is playing the role as the anode.

When the voltage is lower than the forward voltage range, zero current flows through the diode. This is because no electric field can be generated inside the diode and there is an electric barrier at the PN junction. However, when the forward voltage applied to the diode exceeds the value, the electric field will be induced, providing electrons with enough energy to move through the contact surface between the P and N type, enabling the current to flow.

Therefore, BYG20D R3G usually works in two states. In the forward bias, when the applied voltage exceeded 0.7V, the diode will conduct. In the reverse bias, the current cannot pass through the diode even when the voltage is greater than 0.7V. This feature makes it suitable for being applied as a rectifier.

Conclusion

BYG20D R3G is a popular and reliable single diode or rectifier with wide ranging usage and considerable performance in various fields from the small-scale to the heavyweight power supply. Its working principle is based on the combination of the PN junction, allowing it to serve as a powerful voltage regulator in the application.
