FES8HT-E3/45 Working Principle

The working principle of the FES8HT-E3/45 is based on the two diodes inside the device. When the polarity of the input voltage is positive, current flows through the upper diode, while the lower diode is reverse biased. In this state, the current flows in only one direction - from the anode to the cathode. However, when the polarity of the input voltage is reversed, current flows in the opposite direction, through the lower diode. This process of rectification is repeated with each cycle, resulting in an output that only consists of positive half-cycles.

Conclusion

The FES8HT-E3/45 is a single rectifier designed for AC/DC applications requiring high efficiency rectification and extremely low forward voltage. It features ultra-low forward voltage of 0.71V and a fast recovery time, allowing for high efficiency rectification even at high temperatures. The working principle of the device is based on two diodes that allow current to flow in one direction only.
