Current Regulator Diodes
Current Regulating Diodes (CRD) are devices that maintain a constant current flow despite voltage fluctuations. These diodes consist of an n-channel with the gate shorted to the source, which functions like a two-terminal current limiter or current source analogous to a voltage-limiting Zener diode. They allow a current through them to rise to a certain value, and then level off at a specific value. Unlike Zener diodes, these diodes keep the current constant instead of the voltage constant. These devices keep the current flowing through them unchanged when the voltage changes.
InterFET has CRD’s that can operate at load voltages down to 1V and operate up to 50V. Typical applications are current regulation, current limiting, and biasing.
