Diodes are an integral part of the power supply world. They are used to convert AC to DC, to regulate voltage from an AC source, to reduce ringing on problems, to provide overvoltage protection, and to reduce EMI/RFI. Arrays are used as tools for higher currents that are currently unable to be handled by individual devices.The RBQ20NS65AFHTL is one such array device. It is a surface-mount Schottky barrier rectifier, designed for use in power supply and DC/DC converter applications, up to 100V. It has high surge current capabilities and low forward voltage drop.

Working Principle

A rectifier is, in essence, a one-way valve for electricity. Instead of allowing current to flow both directions, as an ordinary conductor would, a rectifier only allows current to flow one way. The RBQ20NS65AFHTL is a Schottky barrier rectifier, which utilizes a Schottky barrier to provide low forward voltage drop, high surge current capability, and low reverse leakage current. The Schottky barrier is created by junction between a metal and a semiconductor, known as a Schottky Diode. The Schottky Diode has a low forward voltage and quick turn-off time compared to a conventional diode, thus allowing for higher power operation and switching frequencies.The RBQ20NS65AFHTL array consists of five separate Schottky diodes, each on its own chip. These are connected in parallel, allowing for a maximum current of 20A and a maximum forward voltage drop of 5.5V.

Application Field

The RBQ20NS65AFHTL can be used in a variety of applications in the power supply and DC/DC converter fields. It is designed for use in hard switching, high speed applications and for applications having high reverse voltage. In multi-phase rectification, the array can be used in a bridge configuration for electric vehicles and solar energy applications. It can also be used in grid connected applications, such as electric power systems and utilities.The RBQ20NS65AFHTL can also be used in a variety of consumer products. It is particularly well suited for powering small, portable electronic appliances and consumer devices, as it offers high surge current, low forward voltage and fast switching capabilities. It is also designed for use in consumer audio and video electronics, such as TVs and DVDs, where it can be used to regulate the power supply and reduce noise caused by the mains supply.

Conclusion

The RBQ20NS65AFHTL is an ideal, cost-effective solution for applications requiring a large current capability and a low forward voltage drop. It is particularly suited for multi-phase rectification, electric vehicles, consumer electronics, and audio and video applications. Its small form factor and surface-mount design make it ideal for high-density applications. With its high surge current capabilities, low forward voltage drop and fast switching times, the RBQ20NS65AFHTL can provide a reliable, efficient power supply solution.
