Introduction

RB095BM-90TL is a diode rectifier array manufactured by Shiga Electric. It is a three-phase diode rectifier array typically used for high-voltage switching applications. This diode rectifier array is a surface-mount technology (SMT) device made of gallium nitride (GaN) technology combined with features that make it suitable for extremely high voltage, high-frequency and high surge applications. It is available in a variety of configurations including bridge, full-wave bridge and full-wave bridge plus capacitor.

Application Field

The RB095BM-90TL diode rectifier array is typically used in applications such as motor drive, power suppression, UPS systems, EV chargers, and AC/DC inverters. It has superior surge immunity which is beneficial in applications where there are large voltage spikes or transients. The device also features voltage standoff of up to 1800V and current ratings of up to 400 A. It is also suitable for high-frequency applications making it a good choice for modern switchmode power supplies.

Working Principle

The diode rectifier array works on the same principle as other diode rectifier circuits. It is based on the forward recovery principle, where a diode is used to convert alternating current (AC) into direct current (DC). The diode is the key component of the rectifier array and its function is to allow the current to flow in one direction only. As the current flows through the diode, it is rectified. The RB095BM-90TL diode rectifier array is a three-phase device, meaning that it converts three alternating current-carrying conductors into three direct current-carrying conductors and a neutral.

Advantages and Limitations

The main advantage of RB095BM-90TL is its superior surge immunity. This makes it suitable for high-voltage, high-frequency applications and allows for long-term operation life. The device also has a wide input voltage range, making it efficient for different input AC voltages. In addition, the device has a low reverse diode recovery time, ensuring fast switching and reduced conduction losses.

Limitations of this diode rectifier array include its cost, which can be quite expensive due to the GaN technology. This device is also only available in surface-mount technology and is not suitable for through-hole mounting. Also, the device is limited by its current ratings, which may be too low for some applications.

Conclusion

The RB095BM-90TL diode rectifier array is a three-phase device that is typically used in high-voltage, high-frequency and high surge applications. It has superior surge immunity and is reliable for long-term operation. It also has a wide input voltage range, low reverse diode recovery time, and is available in surface-mount technology. Its main limitation is its cost and current ratings that may be insufficient for some applications.
