Reverse Recovery Time (trr) - In general terms, reverse
recovery time is a measure of the time needed for a rectifier
diode to reach a state of complete blocking (IR = 0) upon the
application of a reverse bias. Ideally, this time should be
zero. In reality, however, there’s a finite period of time in
which a stored charge at the diode junction must be “swept
away” before the device can enter its blocking mode. This
stored charge is directly related to the amount of forward
current flowing through the device just prior to the application
