Introduction

Diodes are semiconductor devices that allow current to flow in one direction but not in the other. A single diode device, also known as a rectifier or rectifying diode, is a basic form of device used in an array of electronic applications. The SB1H90-E3/73 diode is one such device which is commonly used in amplifiers, switching power supplies, battery charging systems, among other uses. This article aims to explain the application field and working principle of the SB1H90-E3/73 rectifying diode.

Application Field

The SB1H90-E3/73 rectifying diode is generally used in AC to DC conversion, where the alternating current (AC) is converted into the direct current (DC). It is suitable to be used for single-phase full-wave rectifications, where an AC source is connected to the secondary winding of a power transformer. The rectifying diode is connected in series to each secondary side winding of the transformer and rectifies the voltage supplied by the transformer into a DC voltage.The SB1H90-E3/73 diode is also widely used in the power supplies of communication systems, control equipment, and industrial and consumer equipment. It helps to protect components sensitive to high currents by preventing those currents from damaging them.

Working Principle

The working principle of a rectifying diode is based on the fact that current can only flow through the device in one direction and not the other. When a voltage is applied across the diode, it acts as a barrier and prevents current from flowing in the reverse direction. This allows the diode to act as a type of switch, sealing off the device from high voltages and preventing excessive current from flowing.When an AC voltage is applied across the SB1H90-E3/73 rectifying diode, the positive half of the voltage will pass through, allowing the current to flow in one direction. The negative half of the voltage will be blocked by the diode, preventing the current from flowing in that direction. This results in a DC voltage output which can be used in various applications.

Conclusion

The SB1H90-E3/73 diode is a single rectifying diode which is commonly used in AC to DC conversion circuits. It is designed to pass through AC voltages in one direction while preventing DC voltages from flowing in the reverse direction. This allows the device to be used in power supplies and other electronic systems as a form of protection. By understanding the application field and working principles of the SB1H90-E3/73 rectifying diode, engineers can determine if the device is suitable for their own circuits and systems.
