MBRB15H45CTHE3_A/P application field and working principle

Introduction
MBRB15H45CTHE3_A/P is a common form of Schottky diode rectifier array. Schottky diode arrays are designed to provide improved speed, reliability, and efficiency compared to standard diode rectifiers. The MBRB15H45CTHE3_A/P is a 3-phase bridge rectifier in an SO-8 surface mount package. It is rated at 45V, 15A, and comes in an exposed pad package. The array is specifically designed to reduce the on-state losses and EMI noise in switched-mode power supplies (SMPS). The MBRB15H45CTHE3_A/P is manufactured by ON Semiconductor.

Application fields
The MBRB15H45CTHE3_A/P is used in power electronics applications such as SMPS, DC-DC converters, and uninterruptible power supplies (UPS). It can also be used in power supply-rail clamps for up to 45V. It is well suited for use in automotive applications, industrial power supplies, and consumer electronics. The MBRB15H45CTHE3_A/P provides ultra-fast switching, superior efficiency, low EMI, and improved power factor with low power losses.

Working principle
The MBRB15H45CTHE3_A/P is a 3-phase bridge rectifier consisting of six Schottky diodes arranged in three individual bridges. It is designed to provide low power losses and improved power factor compared to standard rectifier combinations. Each of the three bridges consists of two Schottky diodes connected in series with a low forward voltage drop. The forward voltage drop of the device is usually 1.2V at room temperature. The bridge rectifier allows bi-directional current flow, meaning it can convert AC to DC or can provide either positive or negative polarity depending on the application.

The main advantage of the MBRB15H45CTHE3_A/P is its low on-state losses. The Schottky diode design prevents power losses due to the forward voltage drop, enabling the device to effectively transfer power from the AC source to the DC output. The device is also fast switching, which helps reduce power losses due to switching noise. This fast switching also helps reduce EMI noise, making the device suitable for use in sensitive electronic circuits.

The MBRB15H45CTHE3_A/P is suitable for a wide range of applications and has emerged as a preferred choice for power management applications due to its robust design, high efficiency, and low on-state losses. It is perfect for use in SMPS, DC-DC converters, rail clamp applications, UPS, automotive applications, and consumer electronics.}

Conclusion
The MBRB15H45CTHE3_A/P is an efficient, reliable, and cost-effective 3-phase bridge rectifier in an SO-8 package. It offers low on-state losses, fast switching, low EMI, and improved power factor compared to standard rectifiers. The device is suitable for use in SMPS, DC-DC converters, rail clamp applications, UPS, automotive applications, and consumer electronics.
