Current regulating diodes (CRD hereunder) are diodes that maintain a
constant current flow despite voltage fluctuations. CRDs supply constant
current over a wide range of voltage from less than 1V to 100V. Constant
current is supplied regardless of fluctuations in voltage applied, load
resistance changes and ripple voltage. Creating a constant current circuit
generally involves multiple components, but with SEMITEC CRDs only one
part is required to accomplish the same function.
