• Protection against overcharging and reverse polarity in battery charging systems
• Rectification of AC signals to DC signals in medical and industrial applications

Working Principle

The GF1GHE3/67A diode operates using a p–n junction. This is a transition between two distinct layers of semiconductor material consisting of an Assembly of positive holes and negative electrons. When biased in the forward direction, allowing current to flow through the p–n junction and called forward-biased.

The reverse-biased condition occurs when the voltage across the two layers of semiconductor material exceeds the threshold of the diode and prevents current from flowing in the reverse direction.

The diode always has a relatively low forward drop, which decreases the amount of voltage available to operate the load. This drop is caused by both the p–n junction breakdown voltage and the forward resistance of the diode.

The reverse leakage current increases slightly when subjected to higher temperature, but this is of little concern for the majority of applications.

Conclusion

The GF1GHE3/67A diode is a versatile and dependable single rectifier diode suitable for a wide range of applications. It offers reliable rectification and good noise immunity, as well as low forward voltage drop and excellent reverse recovery characteristics.
