In electronics, a step recovery diode (SRD) is a semiconductor junction diode having the ability to generate extremely short pulses. It is also called snap-off diode or charge-storage diode or memory varactor, and has a variety of uses in microwave electronics as pulse generator or
parametric amplifier. When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed.
It is the abruptness with which this reverse current ceases which characterises the step recovery diode.
