The Current Regulative Diode (CRD), which provides a constant current from a low voltage of 3V to 200V over a wide voltage fluctuation range, simplifies the circuit design. The conventional constant current circuit usually requires a complicated multi-component configuration, but CRD can easily realize this design requirement by implementing a single component.
