GBJ2506-G

Diodes - Bridge Rectifiers

A bridge rectifier is an electronic device for converting an alternating current (AC) into a direct current (DC). It is an electrical circuit comprised of four individual soldered diodes in a bridge configuration. The GBJ2506-G bridge rectifier is an industry standard device that can handle a maximum of 540 volts peak at 150 amps.

Application Field

Bridge rectifiers can be found in a variety of electronic applications, from small diode rectifier circuits to large battery charging systems. Bridge rectifiers are commonly used in AC-DC power supplies, motorized power tools, charger circuits, and many other devices.

The GBJ2506-G bridge rectifier is an industry standard device and is often used in applications where the input AC current needs to be converted to DC, such as variable frequency drives, uninterruptible power supplies, and motor speed control. In addition, GBJ2506-G bridge rectifiers are used in automotive and truck charging systems, and other high-voltage DC motor control systems.

Working Principle

The purpose of the bridge rectifier is to convert the AC voltage from an alternating current source into a constant DC voltage. The GBJ2506-G bridge rectifier works on the principle of rectification, which involves converting alternating current (AC) into direct current (DC) by only allowing current to flow in one direction. The four individual soldered diodes in a bridge configuration form an electrical bridge that allows the current to flow through it.

When the AC source is connected to the bridge rectifier, the current flows through the diodes in only one direction. This is because the diodes allow the current to flow when the applied voltage is greater than the forward-bias voltage of the diode—roughly 0.6V. When the voltage is lower than this, the current does not flow. As the AC voltage alternates between maximum and minimum values, the diodes switch on and off in such a way that the output DC voltage is a steady, unidirectional voltage.

The GBJ2506-G bridge rectifier can handle a maximum of 540 volts peak at 150 amps and provides excellent efficiency and reliability in hostile, high-power applications. The device features a low power dissipation and low voltage drop, as well as good thermal coefficients. In addition, it is efficient across a wide range of temperatures, making it an ideal choice for applications where it is needed to withstand extreme temperatures.
