A Rectifier diode refers to the diode acts as electrical device with the main function of changing Alternating Current (AC) into Direct Current(DC.) AC regularly reverses direction, while DC flows in one direction only. Furthermore, it is widely used in power rectifier circuit. Rectifier diodes can be separated into four groups: High Voltage Rectifier (HVR,) Fast Recovery Rectifier (FRR,) High Efficiency Rectifier (HER,) and Super Fast Recovery Rectifier (SFR) by different Reverse Recovery Time (Trr.)

When the forward current stops in a rectifier diode, it will generate a reverse current for a short time. The time span from the forward current stops to the reverse current falls to zero is called Trr.
