SEMITEC E-352

Current regulating diodes (CRD hereunder) are diodes that maintain a constant current fow despite voltage fuctuations. CRDs supply constant current over a wide range of voltage from less than 1V to 100V. Constant current is supplied regardless of fuctuations 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.
