The rectifier diode is also used in power supplies and converters that require a low forward voltage drop. In addition, this diode is commonly used in power electronics applications, including inverters, DC-DC converters, automotive, and industrial control applications. The SD103CW-13 is also well-suited for high-current applications that require low losses and high efficiency. This diode is also found in energy storage applications for energy storage converters or power converters.

Working Principle

The SD103CW-13 rectifier diode is a type of diode that utilizes a junction that is created between P-type and N-Type semiconductor material. The diode then allows current to flow in one direction while blocking the passage of current in the reverse direction. Typically, the junction of a diode consists of a heavily doped N-type layer that is formed on the left side, and a lightly doped P-type layer that is formed on the right side. The thickness of the N-type layer acts as a barrier that blocks current from flowing in the negative direction. When a voltage is applied to the diode, it will cause a current to flow in one direction while blocking the current that is applied in the opposite direction.

At the junction PN, minority carriers are swept from the N-region to the P-region and minority carriers are swept from the P-region to the N-region. This creates a built in potential barrier that keeps electric current from flowing in the opposite direction. This built in potential barrier is referred to as the ‘voltage-blocking’ action of the diode. When a voltage is applied in the reverse direction, the built in potential barrier is reduced, allowing electric current to flow in the opposite direction. This phenomenon is known as ‘reverse-breakdown’.

To allow continuous conduction of electric current, the SD103CW-13 diode is designed to have a reverse-breakdown voltage that is less than the forward-voltage. This allows the diode to have low voltage-drops in forward conduction and fast recovery time during reverse conduction. In addition, this diode has a low NOCT rating and high-speed rectification.

Conclusion

SD103CW-13 is a versatile rectifier diode that is designed for general-purpose, low voltage applications. This diode is well-suited for rectifier applications, switchmode power supplies, and power electronics applications. The diode utilizes a combination of PN junction, built in potential barrier and forward-voltage to allow efficient flow of electricity in one direction while blocking the current in the reverse direction. This diode is also characterized by low voltage drops in forward conduction and fast recovery time during reverse conduction. This makes it an ideal choice for a variety of different applications.
