A '''step recovery diode (SRD)''' is a semiconductor junction diode having the ability to generate extremely short pulses. It is also | A '''step recovery diode (SRD)''' aka '''snap-off diode''' is a semiconductor junction diode having the ability to generate extremely short pulses. | ||

parametric amplifier. | |||
When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed. | When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed. | ||
In SRDs, doping levels are gradually reduced towards the PN junction to maximize the abruptness with which the reverse current ceases. | |||
