AR1PGHM3/85A Diodes are a type of single rectifiers, used for rectifying electric current. As part of the rectifiers, it plays an important role in rectifying electric current from AC to DC. This diode has a variety of identifiable advantages and application fields, which makes it an ideal choice for most rectifying and filtering circuits, especially if the circuit operates at higher frequency or if it needs to bear higher surge currents.

AR1PGHM3/85A application field

AR1PGHM3/85A diodes are widely used as rectifying and filtering components in power supply circuits, radio frequency (RF) applications, and high-frequency switching circuits. They can also be used in high-power rectification equipments.

• DC Motor: In electric vehicle, hybrid vehicle and electric tools, DC motor requires direct power supply to motor. In this case, diodes like AR1PGHM3/85A would be used to rectify AC current to DC current.
• Switching Mode Power Supply: In the modern computer power supply, voltage is converted from DC to AC then back to DC. In this process, AR1PGHM3/85A diodes are used to make sure the final output of power supply is qualitative.
• High-frequency Filtering: In some hi-fi audio equipments, diodes like AR1PGHM3/85A can be used to improve the fidelity of sound. They are also used to filter out noises in the circuits, thus guarantee a noise-free audio output.

AR1PGHM3/85A working principle

AR1PGHM3/85A diodes are designed to convert AC current to DC current. It allows electric current only to flow in one direction, while blocking electric current in the opposite direction. This property of AR1PGHM3/85A makes it possible to convert AC current to DC current. Apart from this rectifying function, AR1PGHM3/85A can also limit the voltage swing on either side of the load. Its structure is both simple and effective. Its forward voltage drop is low, which makes it possible to reduce power loss during the conversion process.

Conclusion

AR1PGHM3/85A Diodes are widely used for rectification and filtering of electric current. It can be used in electric vehicle, power supply, high-frequency filtering, etc. Its working principle and construction are both simple and effective. It has a low forward voltage drop, which makes it an ideal choice of single rectifier.
