GBU10005-G

Diodes – Bridge Rectifiers play an important role in power applications, providing alternating current (AC) to direct current (DC) conversion. In this article, we will discuss the GBU1005-G application field and working principle.

Overview of GBU1005-G

GBU1005-G is one of the popular 1000V products offered by China-based telecoms and components manufacturer Diodes Incorporated. The product is a double centered four-legged metal stud ceramic body bridge rectifier with solderable 6.4mm metal stud terminals. This diode is considered to be a reliable solution for rectifying high voltage in low-cost, low-power applications.

Application Field of GBU1005-G

GBU1005-G bridge rectifier is ideal for voltage conversion and regulation in a variety of applications. It is commonly used in AC/DC converters, UPS systems, industrial power supplies, telecoms power supplies, automotive DC/DC converters, and solar cells. GBU1005-G can also be used for battery charging and discharging as well as rectifying line fed AC power.

Working Principle of GBU1005-G

GBU1005-G bridge rectifier works on the principle of reverse bias of diodes. When the AC input applied across the bridge rectifier is positive (above zero potential), the anode of Diode D1 is biased more negatively than the cathodes of D4 and D2, thus allowing current to flow through the path supplied by D1 and D4. Similarly, when the AC input applied across the bridge rectifier is negative (below zero potential), the anode of Diode D2 is biased more positively than the cathodes of D1 and D3, thus allowing current to flow through the path supplied by D2 and D3. This action of forward and reverse biasing of diodes leads to rectification of the AC input to provide a pulsating DC output.

Advantages of GBU1005-G

GBU1005-G bridge rectifier offers many advantages over its predecessor such as lower reverse clamp voltage, temperature coefficient and capacitance. This makes GBU1005-G more resistant to high frequency interference and provides better immunity from noise compared to traditional rectifiers. Additionally, GBU1005-G is also RoHS compliant and eliminates the use of leaded solder.

Conclusion

In conclusion, GBU1005-G bridge rectifier is an all-purpose rectifier solution offered by Diodes Incorporated. This product is well-suited for high voltage applications in a variety of industries, such as telecoms, automotive, and solar energy. GBU1005-G bridge rectifier also offers many advantages over traditional rectifiers such as lower reverse clamp voltage, temperature coefficient, and capacitance.
