The RB400VAM-50TR is a diode rectifying module which is often used in applications that demand reliable performance such as AC/DC switching power supplies, AC/ DC inverters, residential and commercial solar panels, micro-inverters, low voltage converters, and ultra low-power DC/DC converters. This device has a fast and soft recovery characteristics for switchmode power regulation and for AC-DC bridge rectification applications. It is available in a compact TO-263 package.

The RB400VAM-50TR is a highly efficient diode rectifying module which is designed for reliable operation over a broad current and voltage range. It offers excellent performance in a wide range of temperatures and applications, making it an ideal choice for use in a variety of power supplies, industrial and consumer applications. The device features an optimized body diode recovery time which enables a fast transition from off-state to on-state in high frequency applications.

This diode rectifying module consists of two series connected Schottky Barrier Diodes which are capable of handling up to 50 volts of reverse polarity at up to 400 amperes of load current. The device has the ability to operate at up to 400 volts at 10 amperes of load current, which makes it capable of handling very high voltage and current conditions. The device also features a low static voltage drop and a low dynamic voltage drop which increases efficiency in applications where operating temperature and power dissipation must be managed.

The RB400VAM-50TR operates on the principle of reverse bias or diode clamping. When a negative voltage is applied to the diode it clamps the voltage to the anode, blocking the current flow from the anode to the cathode. The Schottky Barrier Diode allows a larger reverse voltage to flow across the junction due to its lower reverse recovery time compared to a traditional rectifier diode. This allows the diode to operate at higher efficiencies while providing improved power density.

The device is also capable of providing reverse polarity protection and surge protection. When the power supply is first connected, the diode prevents the voltage from entering the system should it have an inverse polarity. This can help reduce the likelihood of system damage and downtime. In surge conditions, the device can limit the surge to an acceptable level, reducing the stress on other components and increasing the life of the system.

The RB400VAM-50TR is also designed to meet UL 94V-0 requirements for flammability. This is important for applications where the diode is installed in an open enclosure or exposed to high temperatures and humidity. It also meets CISPR 22 and FCC Part 15 requirements, making it suitable for residential and commercial use.

The RB400VAM-50TR can offer improved reliability, performance, and efficiency when used in AC/DC and DC/DC switchmode power supplies, AC/DC inverters, micro-inverters, low voltage converters, and AC-DC bridge rectifying applications. Its unique combination of fast recovery and low voltage drop make it ideal for these types of applications. It is available in a compact TO-263 package allowing for easy integration into your system design.
