Working Principle

The MBRB15H50CT-E3/45 is composed of a Schottky rectifier, bipolar transistor, and clamp diodes. The Schottky rectifier serves as the main component of the array, providing precise control of the input current. The bipolar transistor is used to provide overvoltage protection, while the clamp diodes provide enhanced protection from overvoltage surges.

When the input voltage of the SMPS exceeds the maximum regulated voltage (VR, max), the bipolar transistor is triggered, and the current begins to decrease. This, in combination with the clamp diodes, prevents overvoltage damage to the components of the array. Once the input voltage decreases to below VR, max, the bipolar transistor turns off, and the current begins to increase, allowing the SMPS to continue operating in the regulated range.

The MBRB15H50CT-E3/45 is designed to provide precise current control and overvoltage protection in high frequency switched mode power supplies. It is a compact, low profile rectifier array that is suitable for use in a variety of applications.
