Fig.3-24: Symbol for a current regulator diode. Step recovery diode. Rectifier diodes are electronic devices that allow current to flow in only one direction. Mesa-epitaxial 4H-SiC p+-p-no-n+-diodes were fabricated from commercial epitaxial wafers. SemiGen’s SSR series of Step Recovery Diodes are epitaxial silicon varactors which provide high output power and efficiencies in harmonic generator applications. Step recovery diode is similar to these topics: Varicap, Schottky diode, Tunnel diode and more. Using custom epitaxial wafers, our process ensures high reproducibility. The diode is used in a shunt configuration rather than the more usual series circuit, and the result of a simplified analysis relating the basic circuit parameters is given. Step Recovery Diodes have relatively little capacitance change under reverse bias and are used for higher efficiency applications. The state of the art of the step recovery diode (SRD) and its applications are reviewed from the very beginning up to now. It is also called snap-off diode or charge-storage diode or (much less frequently) memory varactor, and has a variety of uses in microwave electronics as pulse generator or parametric amplifier. In electronics, a step recovery diode (SRD) is a semiconductor junction diode having the ability to generate extremely short pulses.
