The SR805HR0G is composed of a single diode junction utilizing a heavy metal oxide semiconductor film. This diode junction is packaged within a four-typed terminal plastic package and is capable of undergoing multiple heat dissipations, depending on the application.

External Parameters

The SR805HR0G is rated for a voltage up to 80 volts and a current of up to 8 amps. It is also categorized as a four junction point rectifier as it is made up of four terminal pins. The total thermal resistance of this diode from junction to ambient environment is 0.8K/W.

Advantages

The SR805HR0G possesses several advantages over other diode rectifiers. Some such advantages include:

• High current rating of up to 8 amps
• High reliability
• Excellent thermal resistance of 0.8K/W
• Compact four terminal plastic package
• Excellent self-recovery characteristics

Working Principle

The SR805HR0G is a diode–rectifier–single and operates based on rectifier principles. A diode is a two-terminal electronic device that allows electrical current to flow in one direction only, effectively converting alternating current (AC) to direct current (DC). The SR805HR0G works by allowing electrons to pass through the p-type and n-type semiconductor layers in its junction, which causes the electrical current to flow in one direction, rectifying the AC current. The SR805HR0G also has a characteristic of self-recovery, meaning that it is capable of repairing itself after experiencing forward recovery, reverse recovery, or transient thermal stress.

Application Fields

The diverse characteristics of the SR805HR0G make it an excellent choice for a variety of applications. The first of such applications is the conversion of AC to DC power. The SR805HR0G is an ideal choice for this conversion due to its rectification capability, high maximum current, and powerful heat dissipation. Additionally, the SR805HR0G can be employed as a power controller, allowing the user to regulate the output of motors or generators. Lastly, the SR805HR0G is useful as an electronic current limiter, protecting electrical circuits from excessive current overloads.

Conclusion

The SR805HR0G is a single-phase rectifier from the DRS field which has multiple versatile applications. It offers impressive characteristics, including a large current rating, a low thermal constant, and a four-point terminal package. Furthermore, it is effective in AC-to-DC power conversion, motor/generator control, and current overload protection. The SR805HR0G is an efficient solution with robust functionality.
