Introduction

FESB16AT-E3/81 is a single phase bridge rectifier that consists of four discrete Schottky Barrier Diodes (SBDs) in a single package. It is widely used in most AC-DC full-wave power circuits, including power supplies, inverters, and motor controllers. This article aims to discuss the application field and working principle of FESB16AT-E3/81.

Application Field

FESB16AT-E3/81 is a single-phase full-wave bridge rectifier which is made up of four Schottky barrier diodes. It is designed to withstand high reverse voltages and provide a harmonic-free output over the entire input cycles of the AC input current. It can be used to convert an AC voltage between 88V AC to 440V AC into a DC voltage. The most common application of FESB16AT-E3/81 is in power supplies. It is also used for rectification of motors in electric trains, in inverters for management and control of motor speeds, and in industrial motor control applications. Additionally, it is commonly used in battery chargers, switch mode power supplies and many other applications.

Working Principle

FESB16AT-E3/81 is a full-wave bridge rectifier that requires an AC input voltage to generate an output DC voltage. It consists of four individual Schottky barrier diodes connected in the form of a "bridge" within the same package. The input AC voltage will be applied across the diagonally opposite diodes in the bridge configuration. When a positive voltage is applied, diode D1 and diode D4 will be forward biased, while diode D2 and diode D3 will be reverse biased. This will allow the current to flow through the diodes and a DC voltage will be generated across the load. Similarly, when a negative voltage is applied, diodes D2 and D3 will be forward biased, whilst D1 and D4 will be reverse biased. This allows the current to flow through the diode in the opposite direction, thereby producing a negative output DC voltage.

The diodes in the FESB16AT-E3/81 package are designed to withstand high reverse voltages and provide an almost harmonic-free output, even when the input AC voltage is not pure sine wave. The maximum reverse voltage of each diode is 200V, and the maximum forward voltage is up to 4V. The forward voltage drop of the FESB16AT-E3/81 is approximately 0.6V and the average reverse leakage current is 5mA, with a maximum of 20mA. The maximum junction temperature of the package is 200°C.
