Ultra Fast Recovery Rectifier Diode is a semiconductor device which possesses short reverse recovery time for rectification purpose at high frequency. A quick recovery time is crucial for rectification of high-frequency AC signal. Diodes are mostly used in rectifiers because they possess ultra-high switching speed.

The fast recovery diode is constructed in the similar manner by which ordinary diode is constructed. The major difference in construction between these diodes and conventional diodes is the presence of recombination centres. In fast recovery diodes, Gold (Au) is added to the semiconductor material. This leads to augmentation in the numerical value of recombination centres due to which the lifetime (?) of charge carriers decreases.
