JFETs as Current Regulator Diodes​​

Current Regulating Diodes (CRDs) are devices that maintain a constant current flow despite voltage fluctuations. These diodes consist of an n-channel JFET 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 JFET-based diodes keep the current constant instead of the voltage constant. These devices ensure that the current flowing through them remains unchanged even when the voltage changes.
InterFET offers CRDs utilizing JFET technology that can operate at load voltages as low as 1V and as high as 50V. Typical applications for these CRDs include current regulation, current limiting, and biasing.
