Diodes - Bridge Rectifiers

Diodes and bridge rectifiers are two important electronic components used in a wide range of applications. Diodes are used to allow current to flow in one direction, while bridge rectifiers allow current to flow in both directions. In this article, we\'ll discuss the application field and working principle of the TB2S-G bridge rectifier.

TB2S-G Application Field

The TB2S-G bridge rectifier is a general purpose, four-pin device commonly used in switching power supplies, DC/DC converters, solid-state relays, power factor correction circuits and pulse transformers. It has no external components and a low voltage drop, making it ideal for use in low-dropout applications. It also features a high-speed soft-recovery characteristics, making it suitable for use in audio circuits, across the line rectifiers, and other high-speed power supplies.

TB2S-G Working Principle

The TB2S-G bridge rectifier is constructed with four diodes arranged in a full-wave rectifying configuration. Current can flow in either direction through the bridge rectifier depending on the voltage across its terminals. The bridge rectifier operates by allowing current flow in one direction through each of the four diodes for each half of the cycle. When current is applied to one side of the rectifier, the current is forced to pass through two of the diodes, allowing current to flow in one direction. During the other half of the cycle, the current is forced to pass through the other two diodes, allowing the current to flow in the opposite direction.

The TB2S-G bridge rectifier is designed to minimize losses and maximize efficiency. It features four independent series diodes, reducing the voltage drop and allowing for a high-speed soft-recovery characteristic. This helps to limit the occurrence of differential mode noise that can originate from other bridge rectifiers. The bridge rectifier also features a built-in anti-parallel diode which helps protect against reverse voltage in high voltage applications.

Conclusion

The TB2S-G bridge rectifier is a general purpose, four-pin device designed for use in a wide variety of applications. It has no external components and a low voltage drop, making it ideal for use in low-dropout applications. The TB2S-G operated by allowing current to flow in one direction through each of the four diodes for each half of the cycle, and it features a high-speed soft-recovery characteristic which helps to limit the occurrence of differential mode noise, as well as a built-in anti-parallel diode which helps protect against reverse voltage in high voltage applications.
