Diodes - Bridge Rectifiers are electronic components used to convert AC power into DC power. They are often used in consumer and industrial electronics applications such as dimmer switches, uninterruptible power supplies (UPSs), and power supply circuits. The most common type of bridge rectifier is the S3BR20, which is composed of three diodes in a bridge configuration. This article will discuss the application field and working principle of S3BR20 bridge rectifiers.

The S3BR20 bridge rectifier can handle up to 2 A of continuous current and up to 3 A of surge current, making it suitable for a variety of consumer electronics applications. It is designed to be used in 120 V AC to 120 V DC circuits with a peak rectified voltage of 140 V. It is also used in applications that require higher input voltages and current capabilities such as industrial or medical power supply circuits. One notable benefit of the S3BR20 bridge rectifier is its low forward voltage drop, which reduces power loss and increases efficiency.

To understand how an S3BR20 bridge rectifier works, it is important to know how a basic diode circuit functions. A diode is an electronic component that allows current to flow in one direction only and blocks the flow of current in the opposite direction. In a basic diode circuit, AC power is applied to the input of the diode. The diode then rectifies the AC power, allowing DC power to flow through the output. This single diode circuit however, will only allow half of the AC waveform to flow through the output. To allow the full AC waveform to flow through the output, a bridge rectifier needs to be used.

An S3BR20 bridge rectifier is composed of three diodes in a bridge configuration. In a bridge rectifier circuit, the AC power is applied to the center terminals of the diodes, and the output is taken from the outer terminals. When AC power is applied to the center terminals, the current flows through two of the diodes, allowing positive and negative cycles of the full AC waveform to flow through the output. The three diodes in the bridge rectifier act as a circuit protector, as only two of the diodes will ever be conducting at a given time. This keeps the current flowing in the correct direction, preventing damage to the circuit.

In addition to its ability to efficiently convert AC to DC power, an S3BR20 bridge rectifier can also be used as an AC switch or filter. Its fast switching time and low forward voltage makes it ideal for use in power converter circuits and voltage regulators. The low forward voltage drop of the S3BR20 also allows it to be used in circuits where low power dissipation is desired. Furthermore, the S3BR20 can be used as a galvanic isolator, providing electrical isolation between the input and output of a circuit.

In conclusion, the S3BR20 is a type of bridge rectifier composed of three diodes and is used to convert AC power into DC power. It can handle up to 2 A of continuous current, is suitable for 120 V AC to 120 V DC circuits and allows for a peak rectified voltage of 140 V. Additionally, the S3BR20 can also be used as an AC switch, filter, or galvanic isolator. This makes the S3BR20 an ideal choice for a variety of consumer and industrial electronics applications.
