Diodes - Bridge Rectifiers: MT800 application field and working principle

Bridge rectifiers have revolutionized the electronics industry by providing direct current (DC) power where AC was previously used. The conventionally used diode rectifier bridges, on the other hand, were designed to transform alternating current (AC) into a direct current voltage. It is extremely essential for ICs to work with direct current; therefore, the use of bridge rectifiers is commonplace. The bridge rectifier has hence had a phenomenal impact on the design of power supplies and other electronic devices.

Amongst these is the MT800 circuit – an 8 ampere (A) DIP Bridge Rectifier that was designed to support dual and single output switching power supplies. The MT800 rectifier featured four diodes in a symmetrical reverse-parallel form, thus enabling efficient transfer of electrical power. It can be up to 20 amperes at 100°C and features a flat surdace-mount case (1.55 x 1.55 x 0.3mm) with super thermal conductivity. The terminal pins of the MT800 are placed on the same end of the component, making it a popular choice for applications in limited spaces such as computers and cellular phones.

Along with its physical features, the MT800 was built to provide economical performance and increased reliability. As the component is essentially a diode array, its application fields extend to the voltage rectification process, with the aim of transforming the input from AC to DC. The current flow in one direction is also enabled due to the rectification component. The component is extremely efficient with current losses of less than 0.08A; dissipating minimal energy in the form of heat at the same time.

The working principle of the MT800 is simple. The response time of the diodes is optimised due to their reverse parallel form, enabling efficient transfer of load over the bridge. The bridge is ultimately a main welding point, allowing for smooth passage of current across the component. The voltages of each diode in the bridge layout proves invaluable in the rectification process, with each diode having its own unique recovery time. A basic bridge rectifier circuit operated by alternating current contains four diodes forming opposite directions of plus (+) and minus (-), facilitating the transformation of AC to DC.

The MT800 is also an extremely reliable component due to its strong build, particularly during extreme environmental conditions. Working temperatures of -55°C to 125°C ensure consistent operation of the component and stress tests prove the component to be effective. The MT800 is also an economical component, with no modifications necessary for use in a range of applications. The component is also a cost efficient solution for many designs and is cost effective for manufacturers too.

To summarise, the MT800 is an incredible component designed to support dual and single output switching power supplies. The component bridges four diodes and operates efficiently due to symmetrical reverse-parallel form, enabling the transformation of AC to DC. It is a reliable component that can work in harsh environmental conditions and is also an economical solution to a range of applications. The MT800 is hence a futuristic solution to electronics designs.
