These include arc welding systems, uninterruptible power supplies, motor drives and control units.

Working Principle

The FR70DR02 is a single phase rectifier diode. Its basic operating principle is the same as all power rectification diodes. It works by converting alternating current (AC) into direct current (DC). The rectifier diode works in a two-step process; when the voltage of the AC current becomes higher than the diode’s threshold voltage, the diode turns on and current is allowed to flow through the diode (“forward bias”). Then, when the voltage drops below the diode’s threshold, the diode switches back off and the current stops flowing (“reverse bias”). This process repeats in each alternating current cycle and effectively converts the AC current into DC current that can be used in various applications.

Summary

The FR70DR02 is a rectifier diode that can be used in a variety of applications for power rectification. It has excellent current stability, high voltage ratings, and pressure contact mounting options, making it a great choice for systems that require reliable and consistent power rectification. Its basic operating principle is the same as all power rectification diodes, converting alternating current (AC) into direct current (DC).
