The MBRB2535CT-E3/81 is a member of a line of rectifier arrays, which are used to convert alternating current (AC) to direct current (DC). The MBRB2535CT-E3/81 is a three-phase rectifier employing Schottky Barrier diodes, which is the latest technology used in rectifier arrays. In this article, we discuss the application field and working principle of the MBRB2535CT-E3/81.

Application Field

The MBRB2535CT-E3/81 rectifier array is suitable for applications with a current open-insulated meter, solar energy grid-tie inverters, adjustable drives for motors, and applications involving uninterrupted power supplies limiting line-side surge current.

The MBRB2535CT-E3/81 can be used in applications with a line voltage of up to 800 volts (V) and peak reverse voltage of up to 600 V. The component can also operate at temperatures from -65 °C to 150 °C, with a thermal resistance of 1.7 °C/W.

Working Principle

The MBRB2535CT-E3/81 functions as a three-phase diode bridge rectifier. A diode bridge rectifier is an arrangement of four or more diodes in a bridge configuration that provides the same polarity of output voltage during either the positive or negative half cycle of the input voltage. In this case, the four diodes are two arms of the bridge, consisting of two high voltage Schottky Barrier diodes each. This arrangement allows the bridge to produce three-phase rectified AC current.

Schottky Barrier diodes are ideal for low-loss transitions between AC and DC. When the Schottky Barrier diode is forward biased (i.e., the anode is positive with respect to the cathode), it behaves as a normal diode and current flows. When it is reverse biased (i.e., the anode is negative with respect to the cathode), the diode does not conduct current. In this way, the Schottky Barrier diode is able to block AC current and then switch it off in order to create a DC output.

The MBRB2535CT-E3/81 rectifier array has a low forward voltage drop, which helps to reduce power loss during AC to DC conversion. Additionally, the low thermal resistance of the component helps to ensure that it maintains its performance without overheating. In this way, the MBRB2535CT-E3/81 is able to accurately and reliably convert AC to DC.

Conclusion

The MBRB2535CT-E3/81 rectifier array is a versatile component that is designed for use in applications involving line-voltage of up to 800V and peak reverse voltage of up to 600 V. Its low forward voltage drop and low thermal resistance help to ensure efficient and reliable AC to DC conversion. The component employs Schottky Barrier diodes, which help to reduce power loss and provide a low-loss transition between AC and DC.
