CRD

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 sub 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.

SEMITEC'S CRDs are fully compliant with RoHS DIRECTIVE2011/65/EU.
