How to form rectifier bridge stack

The rectifier bridge stack product is composed of four rectifier silicon chips connected in a bridge configuration and encapsulated with insulating plastic. The high-power rectifier bridge is encapsulated with a zinc metal shell outside the insulation layer to enhance heat dissipation.

A bridge stack is an electronic component composed of multiple diodes inside.

The main function is rectification, adjusting the direction of current. Using bridge stack rectification is relatively good, firstly it is very convenient, and the four internal diodes are usually selected and paired, so their performance is relatively close. In addition, for high-power rectification, it can be used on the bridge stack

Install heat dissipation blocks to ensure more stable performance during operation. Of course, different bridge stacks should be selected for different usage scenarios, not just based on whether the pressure resistance is sufficient, such as high-frequency characteristics.

There are various types of rectifier bridges, including flat, circular, square, bench shaped (divided into direct insertion and surface mount), and GPP and O/J structures. The maximum rectified current ranges from 0.5A to 100A, and the maximum reverse peak voltage ranges from 50V to 1600V.

Half bridge rectifier is a circuit that combines half of two diode bridge rectifiers together. Two half bridges can form a bridge rectifier circuit, and one half bridge can also form a full wave rectifier circuit with a transformer and a center tap,

Choosing a rectifier bridge should consider the rectifier circuit and operating voltage High quality manufacturers include the G series rectifier bridge stack from Guangzhou Guoxin Electronic Technology Co., Ltd. (Vincent Electronics), and imported brands include ST IR, SEP, GD, and other Taiwanese products. The rectifier bridge stack is generally used for full wave rectification of electricity

On the road, it is divided into full bridge and half bridge.

The full bridge is composed of four rectifier diodes connected in the form of a bridge full wave rectifier circuit and packaged as a whole. The figure shows its appearance.

The forward current of the full bridge has various specifications such as 0.5A, 1A, 1.5A, 2A, 2.5A, 3A, 5A, 10A, 20A, 35A, 50A, etc. The withstand voltage (maximum reverse voltage) is 25V, 50V, 100V, 200V, 300V, 400V, 500V, 600V, 800V, etc

Multiple specifications including 1000V.
