Working Principle

Rectifier diodes act as one-way valves, allowing current to flow in one direction only. When AC is applied to the diode, it will pass it through to the DC side of the circuit, while blocking the opposite direction. This allows for efficient conversion of the current.

The FFSD10120A operates by utilizing various elements of the PN junction to control the current passing through it. The PN junction is composed of two sets of semiconductor materials, a P-type and N-type semiconductor. When the P-type and N-type are connected, a barrier is formed, preventing the flow of current from one side to the other.

When voltage is applied to the diode, it creates an electric field, which allows the electrons of P-type and N-type semiconductors to recombine across the junction. This creates an electron-hole pair, allowing the current to pass through. By controlling the applied voltage, the current can be regulated in one direction, allowing for rectification.

Conclusion

The FFSD10120A rectifier diode is a versatile and reliable semiconductor device, suitable for a range of power supply and related applications. Its features make it a popular choice for its performance and reliability. Understanding its working principle is essential to taking advantage of its features.
