It provides efficient rectification with a low forward voltage drop of 0.59 Volts at 8A and a low reverse leakage current of 0.1 micro-amps. It has a low temperature coefficient of 5 ppm/℃ and an extremely high thermal stability. The device also features a high temperature range of -40°C to +140°C and an operating temperature range of -40°C to +85°C. It is RoHS compliant and is made to meet UL and CSA standards of safety. The device is available in both through-hole and DIP packages for easy installation and replacement.

Working Principle of BU20085S-E3/45

The BU20085S-E3/45 bridge rectifier is an extended common anode type package of 4 diodes connected in the formation of a bridge. It is designed for operation with an input supply voltage of up to 400V and can withstand transients with peak values of up to 500V. The bridge rectifier consists of four controlled diodes arranged in a bridge configuration so that AC input is converted to DC output with a minimum amount of components and without the need for a transformer. The rectifying diodes are connected to the AC input and the DC output terminals in a manner that allows the flow of current through two opposite paths in one direction, thus allowing it to switch directions when the input supply polarity changes. The bridge rectifier has a low forward voltage drop and a low reverse leakage current, both of which help to increase the efficiency of the device and reduce the amount of power lost in the conversion process.

Conclusion

The BU20085S-E3/45 bridge rectifier is an 8 Amp device that is widely used in many applications. It is a low-cost and efficient way to convert AC power to DC power without the need for a transformer. The device features a low forward voltage drop and a low reverse leakage current that help to increase the efficiency of the bridge rectifier as well as reduce power losses. The device meets standards of UL and CSA safety, it is RoHS compliant and it is available in both through-hole and DIP packages for easy installation and replacement. The bridge rectifier is suitable for use in motor drives, switching power supplies and UPS systems, motor controllers, and in many other applications.
