Diodes are electrical components with various applications, such as limiting and rectifying electric current and voltage in circuits. Bridge rectifier diodes - of which the VUO82-18NO7 is a type - are large semiconductors that consist of four diodes arranged in a bridge configuration, producing a full-wave output rectifier. This component revolutionized power supplies because it does away with bulky transformers and allows for the production of pulsating DC current.

Structure and Specifications

VUO82-18NO7 bridge rectifier diodes are comprised of four individual diodes and integrated with a surge protection capacitor and a current limiting resistor. Its case is a V-shaped holder, with an E case and additional components mounted on top. Its peak forward surge current is 120A, with a forward voltage of 18V. Its reverse current is 5µA, and it has a reverse voltage of 72V. Its power dissipation is 1.2 watt and an operating temperature of -55 to +175 °C.

Working Principle

The VUO82-18NO7 bridge rectifier diode converts alternating current (AC) to direct current (DC) by using its four interconnected diodes in a bridge formation. The four diodes alternate to allow current to flow on one side of the rectifier while blocking it on the other side. This creates a full-wave output that provides two AC half-cycles, allowing it to rectify the input AC voltage and turn it into pulsating DC voltage. A capacitor is used to filter the pulsation to provide a more steady DC voltage.

Uses

Bridge rectifier diodes can be used in a variety of applications such as telecommunications and power supplies. The VUO82-18NO7 bridge rectifier diode is designed for use in AC/DC power supplies and low-voltage electronic projects, such as those powered by batteries or wall outlets. It can also be used in appliances such as air conditioners, refrigerators, fans, and televisions. With its low voltage and high current capabilities, the VUO82-18NO7 can withstand power spikes or surges and ensure that the current provided is as steady and reliable as possible.

Conclusion

The VUO82-18NO7 bridge rectifier diode is a versatile component that is capable of converting alternating current to direct current efficiently and reliably. While it has many uses, it is especially useful in AC/DC power supplies and low-voltage electronic projects. With its surge protection and current limiting features, the VUO82-18NO7 is the perfect choice for a variety of applications.
