Fast Recovery Diode (FRD) is a kind of semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in electronic circuits such as switching power supply, PWM pulse width modulator and inverter, as high frequency Rectifier Diode. Use for freewheeling diodes or damper diodes. The internal structure of the fast recovery diode is different from that of a normal PN junction diode. It belongs to a PIN junction diode, which adds a base region I between the P-type silicon material and the N-type silicon material to form a PIN silicon wafer. Since the base region is thin and the reverse recovery charge is small, the reverse recovery diode has a short reverse recovery time, a low forward voltage drop, and a high reverse breakdown voltage (withstand voltage value).
