Diodes – Bridge Rectifiers
A diode bridge rectifier is a component often found in the electrical power supply circuits of commercial electrical equipment. It consists of four diodes connected to form a bridge configuration which provides a low impedance path for current to pass so that the full output voltage of the transformer is transmitted to the load. The diode bridge rectifier is a great way to make sure the reverse current doesn’t harm your equipment.
What is the GBJ1004TB?
The GBJ1004TB is a two-terminal, single-phase bridge rectifier with four diodes in a single package. It is designed for easy replacement of existing diodes in many applications. The device has full wave rectification, with integral fast recovery diodes for better conduction efficiency and lower thermal losses. It is widely used in commercial AC-to-DC power supplies, motor controls, and other low voltage switched mode applications where space is at a premium.
Application Field and Working Principle
The GBJ1004TB bridge rectifier is suitable for use in applications where a low voltage DC supply is required, such as DC power supplies, motor drives, and other low-voltage switched mode applications. Its four diodes are connected in a bridge circuit, meaning that they can be used to convert alternating current (AC) to direct current (DC). When current flows through the bridge rectifier, the diodes are alternately blocked, allowing the AC current to pass through one of the two paths. The resistance of the four diodes combined is what makes sure that full voltage of the AC input is transferred to the output.
The bridge rectifier has several advantages over other rectification methods, such as the half-wave rectifier, making it a popular choice. For example, it can handle higher current loads than half-wave rectifiers and can provide smoother current flow. In addition, the bridge rectifier is capable of providing near-perfect conversion from AC to DC with very little loss, making it ideal for applications where higher efficiency is required.
Conclusion
The GBJ1004TB bridge rectifier is a two-terminal, single-phase device with four diodes in a single package. It is suitable for use in applications where a low voltage DC supply is required and provides full wave rectification with integral fast recovery diodes for better conduction efficiency and lower thermal losses. The GBJ1004TB is a great choice for those who need high efficiency and reliable operation in a small form factor.
