Working Principle of FFA40U60DNTU

FFA40U60DNTU is a type of fast-recovery rectifier that works based on the principle of Schottky barrier rectification. The working principle of FFA40U60DNTU is based on the PN junction between the two dissimilar materials such as metal and semiconductors. The FFA40U60DNTU consists of four rectifiers connected in series. When a positive voltage is applied to the anode of the rectifier and a negative voltage is applied to the cathode of the rectifier, current flows from the anode to the cathode. The current carrying capability of FFA40U60DNTU is very high due to its fast recovery time.

When the voltage at the anode of the rectifier rises above the reverse breakdown voltage, the rectifier turns on and starts to conduct current. This is known as the forward conduction mode. In the forward conduction mode, the rectifier acts as a short circuit and high current flows from the anode to the cathode. As the anode voltage increases further, the voltage across the rectifier reduces and eventually reaches a level that is equal to the voltage of the anode. At this point, the rectifier turns off and the current flowing through the rectifier reduces to zero. This is known as the reverse conduction mode.

The FFA40U60DNTU rectifier array is an ideal choice for high-power applications due to its fast recovery time and high current carrying capability. It also provides excellent thermal stability in high-temperature conditions, making it ideal for use in extreme operating environment.
