MBRB1545CT-E3/81

Diodes Rectifiers - Arrays represent an assortment of technologies widely used in today\'s electronic applications. They are used to convert alternating current (AC) to direct current (DC) and also to provide noise reduction and power conditioning. In this article, we will explore the application field and working principle of the MBRB1545CT-E3/81.

This product is a Central Semiconductor full bridge rectifier designed for use in high frequency switching applications. It is specifically intended for power factor correction (PFC) circuits and active PFC circuits. Being a full-bridge rectifier, it consists of four diodes that act as a bridge carrying the entire forward current of the device. As a result, the MBRB1545CT-E3/81 is especially suitable for power applications requiring high efficiency and low power dissipation.

The MBRB1545CT-E3/81 is rated at 15A, 400V and is compliant with international safety standards. It is available in an E3/81 package with a maximum junction temperature of 155 °C, allowing for safe and reliable operation in a variety of applications. This robust package can also withstand high-energy pulses and is certified to UL1577.

The working principle of this device is based on the fact that when the diodes are forward biased, they act as a low resistance path to the return circuit. This causes the AC current to flow through the bridge rather than around it. The resulting effect is that when power is applied to the MBRB1545CT-E3/81, the diodes conduct a reverse current that is rectified to a DC voltage. The output of the rectifier is then filtered to provide a smooth DC output.

The MBRB1545CT-E3/81 is used in a wide range of power electronic applications such as uninterruptible power supplies (UPS), DC/DC converter circuits, inverter circuits, and motor control circuits. It can also be used in lighting systems and can provide high-efficiency and low-cost PFC solutions.

In summary, the MBRB1545CT-E3/81 is a high-efficiency and low-power dissipation rectifier designed for power factor correction and high frequency switching applications. It is rated at 15A, 400V and is compliant with international safety standards. It offers excellent performance, robustness and reliability for many power-electronic applications.
